Unfortunately, this time it really is.
It absolutely is not. At the VERY least, the entirety of the republican party is to blame for sucking PedoTUS's dick so hard he thinks he can nuke Iran. His cabinet could 25th him and get rid of him right now. Republicans in congress could impeach him (which wouldn't be nearly as quick, but they could make it move if they actually cared).
Do not let those assholes do a face turn and forget that they were more than happy to support trump until the ship was damn near sunk.
