Ohio Gov. John Kasich (R) warned on Sunday that the U.S. is walking away from international alliances and guidelines that were put in place after World War II as a means of preventing authoritarianism.
"One of the things I am concerned about is the drift that we are in right now in terms of America and the world," Kasich told NBC's Chuck Todd on "Meet the Press."
"There is an issue here where we're weakening the things that we put in place after World War II to keep the world safe and reflect our values. We can't afford to walk away, Chuck. Because if we walk away, this thing collapses. And who wins? The authoritarians. The Russians and the Chinese. Not good for our country, and not good for freedom," he said.
"There is a battle now. The Russians and the Chinese want authoritarian-type government, okay? And we're walking away from our allies on trade agreements, this Iran thing, we'll see how that turns out," he continued.
Kasich's comments come after Trump dealt a blow to the 2015 Iran nuclear deal on Friday, announcing the deal was not in U.S. national security interests.
The president stopped short of withdrawing from the deal, but threatened to kill the Obama-era pact if Congress did not come back with "satisfactory" changes to the accord.
The announcement was met with backlash from Trump's critics, as well as key European allies of the U.S.
The administration has put the international community on edge in the past, with the U.S.'s departure from the Paris Climate Accord, as well as Trump's past negative rhetoric on the North Atlantic Treaty Organization.
