Congress has approved legislation that would prevent any president from withdrawing the United States from NATO without approval from the Senate or an Act of Congress. The measure, spearheaded by Sens. Tim Kaine (D-Va.) and Marco Rubio (R-Fla.), was included in the annual National Defense Authorization Act, which passed out of the House on Thursday and is expected to be signed by President Biden.
It is funny because it is the opposite actually. Former senates and presidents actually clashed over foreign policies, it is only in recent times that presidents were more or less left to decide. So, I guess there is a bit of projection going on here.
