Did Biden just escalate the Gaza War?

Since the beginning of President Donald Trump’s second term, there have been ongoing diplomatic efforts to broker a peace settlement in the three-year-long war between Russia and Ukraine. So far, however, negotiations have failed to bridge the stark divide between the two sides.

Two of the key contentious issues have been post-war security guarantees for Ukraine and the political status of Ukrainian territory claimed or annexed by Russia. Specifically, regarding territorial sovereignty, Ukraine and Russia have rejected the United States' proposal to “freeze” the war along the current line of conflict as a de facto new border. Ukraine has refused to renounce its claims of sovereignty over territories occupied by Russia (including Crimea, which was annexed in 2014). Russia, in turn, has demanded Ukraine’s recognition of Russia’s territorial claim over the entirety of the four Ukrainian regions, which Russia annexed in 2022.
