I'm not very good at predictions but it's a got the potential of becoming an epic dumpster fire.
I had no problem with the targeting of Iran nuke facilities. Trump even had the tacit support of Hillary Clinton, of all people, for those strikes. But he should've backed off after that. If there's one thing we've learned through modern history is that with very few exceptions air power alone ain't enough to effect a regime change. If anything, all it does is cement a people's will to resist.
And it's hard for me to believe that he might've actually thought that air strikes would trigger a grassroots revolution by unarmed people against a hardcore IRGC that massacred demonstrators by the thousands last winter.
As far as Pakistan getting involved, aren't they a bit busy in Afghanistan right now?
