Do you think the United States should interfere with other countries affairs?

I personally think that the US get into others countries affairs way too often. I understand that yes sometimes other countries do need some help and there is a good time to help. But when they obviously do not need help (from another country or the us to say the least) then why would we go in. The US really needs to focus on all of its problems at home before it even thinks about trying to help others. I think for some reason since the small amount of help we sent during WWII helped so drastically the US feels as though they can help everyone in need even if our own country is collapsing beneath out feet.
