Republican vice presidential nominee JD Vance said at the 2024 Republican National Convention (RNC) in Milwaukee, Wisconsin, that a Trump presidency would not mean "free rides" for the US allies in sharing the burden of securing international peace.

Vance also added that the US will only wage wars when necessary. 

On Wednesday, he said, "Together, we will make sure our allies share in the burden of securing world peace. No more free rides for nations that betray the generosity of the American taxpayer. Together, we will send our kids to war only when we must ... When we punch, we're going to punch hard."

Vance is well-known for opposing the US military's multibillion-dollar help to Ukraine and advocating for negotiations with Russia. Additionally, he exhorts the US government to focus on China's competitors. In terms of domestic politics, he is in favor of strengthening immigration laws and outlawing abortion. 

Two days ago during an interview for Fox News, Vance outlined two key actions: first, ending the war as swiftly as possible to prevent worsening "Israel’s" situation, and second, resuming normalization talks between "Israel" and Saudi Arabia. He also stressed that former US President Donald Trump was "Israel’s" strongest ally.

Trump announced via the social media platform Truth Social on Monday that he has chosen Vance as his running mate for the 2024 presidential race.

However, a recent Politico article cited a senior EU official describing Vance's appointment as a "disaster" for Ukraine and the EU, both of which are heavily invested in funding the war with Russia. The official told Politico that Vance's influence could lead to significant reductions in US aid to Ukraine and undermine efforts to support Kiev.

Vance's economic protectionism also poses a challenge to Europe. Known for his advocacy of American manufacturing and support for tariffs on imports, Vance's policies could strain the transatlantic trade relationship. During a recent interview, Vance stressed the need for the US to focus on domestic production capabilities rather than prolonged foreign engagements, a stance that resonates with Trump's "America First" policy.
