I can promise you that I will be as critical on Democratic presidents that fuck up foreign policy as I am on Republicans.
Obama should have pulled out of Afghanistan. That was his biggest FP mistake, by far. Using the phrase “red line” regarding Syria was a mistake - but refusing to intervene was not. It’s ok for great powers to bluff sometimes.
If president Biden (or whoever) were to get us into war with Iran, I will hate him for it.
