To be against Israel is to be against the USA because they are connected at the hip, like it or not. The Balfour Declaration happened. The formation of Israel happened. These "America First" nuts need to get over it.
We're never going to "get over it," as long as there are people like you out there who believe that American blood should be spilled defending Israel, or any other nation for that matter besides the good old USA.
Tell me something. Do you want your children or grand children to die defending Israel? If no, you're a hypocrite.
America First nutballs indeed.
