Here is more from the New York Times, in a piece entitled "Why the Once-Hawkish Heritage Foundation Opposed Aid to Ukraine":
Hours before the House voted this month to approve $40 billion in military and humanitarian aid for Ukraine, lobbyists affiliated with the Heritage Foundation, the prominent conservative think tank, were privately pressing Republicans to oppose the measure.
For years, the group advocated a hawkish foreign policy, enthusiastically backing the wars in Iraq and Afghanistan, and, more recently, criticizing President Barack Obama for “always” seeking “to find the absolute minimum level of military power he can get away with.”
But more recently, its lobbying arm has embraced the anti-interventionist fervor that defined President Donald J. Trump’s foreign policy and has swept the Republican Party.
In a tweet, E.J. Fagan, an Assistant Professor of Political Science at the University of Illinois, said "I might have read more Heritage Foundation reports than any person who hasn't worked there...It's hard to overstate what a seismic change Heritage becoming pro-Russian is. They've ditched Ronald Reagan and fully bought into Donald Trump."
In another tweet, Joseph Collins, Director of the Center for Complex Operations at the National Defense University (NDU), said that "returning to the GOP's isolationist roots, the Heritage Fndtn follows the MAGA mob...Glad to have quit them 2 yrs ago."
