You cooperate with one president and he makes promises. Then along comes another president intent on destroying anything the previous president accomplished. So, you get thrown to the wolves. It will be a century before we overcome the damage Obama has done to the country’s integrity. (Assuming we ever do.) He has betrayed South Korea and Poland, to name just two.
It is always the democrats that deny our allies support. Started with Jimmy Carter’s Nixonion congress critters and the fall of Saigon.
Poland I remember but please remind me about South Korea.
