Iran has been a supporter of terror ever since the Dems (Carter) let the Shah fall. There's no reason for them not to act since the Biden regime has been kissing their butts since day one and transferred billions to them and dropped sanctions.
The debacle in Afghanistan showed Putin that the current regime here is incompetent beyond belief and ideologically driven to weaken America. Coupled with the "flexibility" Obama's regime offered after the 2014 invasion (and many of them are back in power), there was no compelling reason for Putin not to invade Ukraine. Remember the Biden regime was willing to write-off Ukraine and offer Zelensky a ride out. Only their resistance embarrassed them enough to provide grudging support.
Even though Trump wanted US forces out of the ME when Wagner units threatened US forces in Syria he had the US military grease 300+ Russian mercs. Trump would have maintained tough sanctions on Iran and Putin would never have dared to attack Ukraine if Trump hadn't been forced from office by a fraudulent election.
Bull feces.
The Ukraine proxy war was completely started by the United States.
We are no longer the good guys, if we ever were.
