On Thursday morning, Russian President Vladimir Putin announced the start of a large-scale military action in Ukraine's Donbas. According to former Ukrainian President Petro Poroshenko, Russian soldiers initiated a large military operation in Kharkiv, Ukraine. Russian troops are reportedly prepared to enter into Ukraine from the Crimean Peninsula. A tense border between Ukraine and Russia has been developing for weeks. The US claims Russian President Vladimir Putin planned to attack Ukraine long ago.

Russia-Ukraine tensions date back to the “Middle Ages”. Both Russia and Belarus have roots in the East Slavic kingdom of Kievan Rus', according to Russian President Vladimir Putin. Despite their common ancestors, these two countries developed independent languages and civilizations. So while Ukraine couldn't establish itself, Russia expanded into an empire. Since 1917, when Russia's empire crumbled, a large section of what is now Ukraine was forcefully reoccupied by Soviet Russia.

Even though Ukraine and Belarus helped overthrow Soviet domination in December 1991, Moscow tried to maintain its status by creating the Commonwealth of Independent States. The Kremlin thought it could influence Ukraine by supplying cheap gas. While Russia and Belarus have a close relationship, Ukraine has traditionally looked west. Contrary to popular belief, Russia was not unhappy with the Ukrainian government's pro-Western stance in the 1990s since Moscow kept mute, the West did not strive to integrate Ukraine, and the Russian economy was struggling.

Russia was obsessed with the Chechnya conflict. Moscow officially recognized Ukraine's borders and Crimea's Russian-speaking population in 1997. When the Soviet Union collapsed in the early 1990s, Ukraine held the world's third-largest nuclear arsenal. They worked together to denuclearize Ukraine in exchange for security guarantees against a potential Russian attack. Kiev handed Russia hundreds of nukes. Moscow and Kiev had their first real diplomatic crisis under Putin. Vladimir Putin began building a dam in the Kerch Strait in Kosa Tusla in 2003.

When the Russian and Ukrainian presidents met, they addressed the issue by agreeing to redraw the country's borders. When the dam project was stalled, the two countries' ties began to erode. As a result of the "Orange Revolution," Viktor Yushchenko, a pro-Western politician, defeated Viktor Yanukovych in the 2004 Ukrainian presidential elections. To Ukraine's surprise, Russia cut off gas supply twice in 2006 and 2009.

The Bush administration's aim to integrate Ukraine and Georgia into NATO and accept their membership through an initial preparation program in 2008 was greeted with Russian President Vladimir Putin's rejection." Bush's proposal was foiled by France and Germany, and while Ukraine and Georgia joined NATO during the Bucharest summit, no timeframe was set. Because joining NATO took longer than expected, Ukraine sought a partnership with the EU.

In the summer of 2013, Moscow placed heavy economic sanctions on Kiev and restricted imports. In light of this, the Yanukovych government suspended the pact, sparking a wave of protests. He was detained in Russia in February, and Russia annexes Crimea. A political vacuum in Kiev allowed Moscow to seize Crimea in March 2014, marking the start of an unofficial war. So when Donetsk and Luhansk declared themselves people's republics, Russian paramilitary forces joined the fight. After the May 2014 presidential elections, the Kiev administration started a major military operation dubbed the "War on Terror."

The "Normandy Format" was also created at a June 2014 meeting between newly elected Ukrainian President Petro Poroshenko and Russian President Vladimir Putin commemorating the 70th anniversary of D-Day landings. In September, a Minsk peace agreement ended hostilities on a larger front by defeating Ukrainian military elements in Ilovaisk, east Donetsk. A proxy war rages in Donbas and in early 2015 the rebels began an onslaught on Kiev, supported by Russian forces without identification, which Moscow denied. Kiev alleges Russian soldiers assisted the offensive.

The attack on Debaltseve, which compelled the Ukrainian army to leave in a manner close to escape, cost the Ukrainian forces a second loss. Although its conditions have not yet been fully implemented, "Minsk 2" was agreed upon under Western auspices at the time. In the fall of 2019, the two warring sides succeeded in evacuating forces from many battle zones; but no meetings since the December 2019 Normandy conference in Paris. Seeing Ukraine's current president, Volodymyr Zelensky, would be a waste of time for Putin.

Since December 2021, Russia's President Vladimir Putin has publicly urged the US not to allow Ukraine's NATO membership or military assistance. President Putin is deeply disturbed by the thought of Ukraine joining NATO. According to Chapter V of the "NATO" pact, any attack on a NATO member constitutes an attack on all 27 members, putting Russia in direct confrontation with the US, UK, and France.

First, in the spring of 2021, Putin gathered military people and equipment along the Ukrainian border, attracting the attention of the US, which sought to meet with Putin and Vice President Biden. Meanwhile, Putin's views on the US have shifted dramatically, especially after the haphazard US military departure from Afghanistan and the division that followed the previous presidential elections, which Moscow regards as proof of American weakness. Vladimir Putin sees the West as fundamentally split on the role of the United States, and President Biden is still working to mend the transatlantic partnership after the level of distrust established under former US President Donald Trump's term. In addition, France was surprised by Biden's nuclear submarine deal with the UK and Australia.

Ukraine’s aspirations to join NATO raised concerns about a Western military presence on Russia's borders. Because, as Putin stated, "we must make this totally definite," Russia's deputy foreign minister Sergei Ryabkov says Russia "needs a legally binding promise" that NATO would not expand. Most Donbas residents speak Russian; hence 720,000 of the almost 3.5 million residents have Russian passports. In eastern Ukraine, the Russian government has long aided and backed Ukrainian insurgents.

In mid-week polls, Donbas residents favored the Russian government. The next day, the Donetsk and Luhansk parliaments agreed to protect any Russian military operation in eastern Ukraine if Russia recognized the two territories. Averting a financial catastrophe in Europe by blocking "Nord Stream 2," the gas pipeline linking Russia to Germany and then to the rest of Europe, Western nations may impose pressure on Moscow.

Russia began massing soldiers along the Ukrainian border in November. In his address on Monday, Russian President Vladimir Putin acknowledged separatist-controlled areas of Ukraine's two regions as separate entities. Putin says Ukraine has no history and its leaders are corrupt. When the Russian army topped 100,000 soldiers on February 15, a spokesperson for the Russian Defense Ministry claimed certain army units "had already started placing their equipment onto trains and wagons; today they will start returning." After Russia's statement, NATO Secretary General Jens Stoltenberg said the alliance "constantly moves forces forward and backward." The alliance's forces have always moved right, left, forward, and backward. Russian military capabilities have progressively increased along Ukraine's borders in recent months.

The international community looks with caution at the heated situation between Russia and Ukraine. The Secretary-General of the United Nations, as well as China, have called for calm and dialogue. On the other hand, the Russian President considers that this decision was inevitable and Russia is achieving its strategic goals in Ukraine.
