Trump is the big wildcard though
on numerous occasions during his short spell of presidency, he has shown the tendency to do exactly what everyone warning him not to do if for nothing else just to see what happens if he did. What makes you guys think that attacking Iran would be too different ?
I suppose he does still need an approval from Congress for a full scale war and doubt he will be given such but i can certainly see him pulling off a surgical attack of sorts just to send a message of intent and to give it one more push to finally force Iran to come to negotiating table with him.
If attacking Iran helps him, he will do it. A lot of his political opponents who also hate him right now, will love him if he attacks Iran.
