President Joe Biden's apparent decision to allow Ukraine to use US-made long-range missiles to attack targets within Russia has caused significant backlash from allies of former President Donald Trump.

Although Trump has remained silent on the matter, his son, Donald Trump Jr., accused Biden of trying to provoke World War III.

Biden has already committed substantial financial support to Ukraine but reportedly dropped a previous restriction on striking Russian targets with American weapons.

While formal confirmation of this change is absent, some high-profile Republicans, like Rep. Marjorie Taylor Greene, have openly criticized the move, reflecting a sentiment among a portion of the Republican base that opposes US involvement in foreign conflicts.

Polls indicate a large number of Republicans are against continued support for Ukraine.

Trump's former national security adviser, James Gilmore, suggested that any Biden administration delay in providing these capabilities to Ukraine was problematic.

Biden's decision also comes in light of reports about Russia's increasing use of North Korean soldiers in the conflict.

Despite potential strategic benefits, Trump's camp remains critical, with many advocating reduced involvement in foreign wars.

The reaction from Russian President Vladimir Putin has been cautious but foreboding, as Moscow warns of repercussions.

Russia has labeled each Western military aid package as direct involvement in the conflict, with significant concern over the implications of long-range missile availability to Ukraine.

Experts suggest this development may pressure Russia to adopt a more cautious approach.

The US decision aligns with reports of increasing Russian aggression in Ukraine, which has prompted the reconsideration of Western military support.
