"The Cheney/Graham neocon War Caucus wants to come back to DC and declare a war. My question for them is - who will you declare it on?" he tweeted Wednesday.

"Will it be out NATO allies the Turks? Will it be Assad? Will it be Islamic rebels? Which ones? They want to keep starting endless wars in conflicts that go back hundreds of years, but what they want makes no sense," he added.

"I know this @realDonaldTrump is the first President in my lifetime to understand what is our national interest and what is not. He is stopping the endless wars and we will be stronger as a result. The Cheney/Graham Neocon War Caucus has cost us too much fighting endless wars," Graham continued in his tweet thread.

Paul's comments came after the two Republican lawmakers broke with Trump following the White House announcement that Turkey would be "moving forward with its long-planned operation into Northern Syria" and that U.S. troops "will no longer be in the immediate area."

Cheney called the move “a catastrophic mistake” and Graham has said the decision could put the nation and Trump's presidency at risk.

Paul, who identifies as a libertarian, has praised the decision, tweeting Monday: "I stand with @realDonaldTrump today as he once again fulfills his promises to stop our endless wars and have a true America First foreign policy."

Trump said Wednesday on Twitter that 50 U.S. soldiers had been removed from the region.

Turkish President Recep Tayyip Erdoğan also said Wednesday that his nation's military and a Syrian militia started an operation against Kurdish forces in northern Syria.

Paul and Cheney have previously sparred on Twitter, with the House Republican Conference chairwoman claiming Paul’s motto is “terrorists first” while the senator accused Cheney of "warmongering."
