Here is more from Politico:
Thomas Spoehr tendered his resignation last week as director of the Heritage Foundation’s Center for National Defense, people familiar with the decision tell NatSec Daily, citing the think tank’s increasingly skeptical stance on supporting Ukraine as one reason for his departure.
Spoehr's last day at Heritage will be Sept. 1.
As the National Review (NR) noted, Heritage has recently pivoted away from its historically hawkish position on Russia. It also notes that the think tank has rolled out a public messaging campaign that attacks continued US assistance to Ukraine for allegedly holding up disaster relief funding that could be distributed to Americans.
NR adds that over the past year and a half, the think tank "has executed a pivot toward what its top executives bill as a third-way foreign policy that is neither interventionist nor isolationist, roiling the conservative policy world." It adds that dozens of former Heritage staffers left the think tank in 2022, with many citing a more nationalist stance as the reason for departure.
