As hostilities continue between Israel and the Palestinian terrorist group Hamas, prominent Republicans are weighing in on the matter. The commentary coming from Republicans highlights the debate between those who favor a more interventionist approach and those who believe America should stay out of foreign conflicts.

On Saturday, former Vice President Mike Pence lashed out at former President Donald Trump and others in the GOP for being “voices of appeasement” in their stances on foreign policy.

Former Vice President Mike Pence tore into Donald Trump and pointed to isolationism in the Republican Party as complicit in the sweeping Hamas attack on Israel, decrying American “retreat on the world stage.”

In a scathing rebuke, Pence faulted “voices of appeasement like Donald Trump, Vivek Ramaswamy and Ron DeSantis that I believe have run contrary to the tradition in our party that America is the leader of the free world.”

Pence’s comments in Iowa represented the first ripple in the Republican primary from the violence that erupted on Saturday — and effectively threw down a challenge to Republicans he said have “embraced the language of isolationism and appeasement.”

Pence has made foreign policy a central issue in his campaign, specifically when it comes to the U.S. backing Ukraine in its conflict with Russia. He became the first Republican presidential candidate to meet with Ukrainian President Volodymyr Zelensky.

The former vice president also railed against the Biden administration in a post on social media, accusing him of projecting “weakness on the world stage.”

This is what happens when @POTUS projects weakness on the world stage, kowtows to the mullahs in Iran with a $6 Billion ransom, and leaders in the Republican Party signal American retreat as Leader of the Free World. Weakness arouses Evil. https://t.co/ONIdaTaksH

The issue surrounding Pence’s criticisms is a Republican Party that is continuing to go through an ideological realignment. The conservative movement, in large part, has moved beyond the days of Neocon foreign policy, and is increasingly supporting less intervention in foreign affairs. Pence, along with people like former U.N. Ambassador Nikki Haley have held on to the idea that the United States should remain involved overseas. Both are ardent proponents of U.S. military aid to Ukraine.

On the other side, people like Trump and entrepreneur Vivek Ramaswamy advocate for a more non-interventionist approach. The former president frequently promised to keep America out of endless wars overseas and focus on America’s needs first.

Given the fact that more polls show that conservative voters oppose continuing military aid to Ukraine, it seems to suggest that the non-interventionist faction of the movement is winning out. After having gone through the war on terror and the decades-long war in Afghanistan, many Americans are no longer keen on the idea of being intertwined with global conflicts – especially those that do not directly affect the United States.

As the GOP grapples with this internal debate, it will likely affect the evolving landscape of American politics when it comes to international relations. At this point, it seems apparent that the days of the Republican war hawk era are finished for the time being.
