Mainland US, no. They may try a military base near them. If they do anything. However even countries they consider allies have told them if they make a move they are on their own. So it is highly unlikely.
They said they are going to but on the other hand their jus killing them selves because their army is no match for our but were trying to prevent as much war as possible but we can easily take them out but we don't want to send a Nuke because it will jus start war and to many innocent people so yeah If they do it won't really effect us as much as think
