I agree John McCain or Lindsey Graham were (are) total morons on Syria strategy, but they never were in a position to implement anything, just to bloviate. The policies implemented were all Obama/Clinton.
They lobbied very hard for the Obama policy he implemented.
One could easily say it wouldn’t have been implemented without them.
I say this, because John and Lindsey provided cover for him. He could point to them and say it was an effort supported by both parties.
I understand your point, and technically you’re right. In the real world, they’re as guilty as he is > IMO.
