I wouldn’t call them isolationists.
They actually thought it was a great idea to remove Khadafi.
I thought the Muslim Brotherhood would be as bad as he was if not worse.
Isolationists are another problem. There are times when we have to go in. Libya wasn’t one of them, and we had no business butting funding and arms in to the terrorists.
The problem with removing a cancerous dictator is you don’t really know what will come in next to fill the void.
Better the devil you know. Same argument could be made about Saddam Hussein. Or Bashar al Assad.
