Of course there is 'more than just some truth in it'.

One is that there is an all-out Iranian military intervention in Syria going on since 6 years, with the IRGC-QF controlling and providing for up to 250,000 troops there (including locals)...

...another is that there is no Syria even in form of an 'Assad Regime' actually left worth talking about, because everything there is de-facto IRGC-QF-controlled...

...and yet all of the West can't find a single Pasdaran in all of Syria, and don't anybody dare touching that nuclear treaty.

...while all are crying foul about three (in digits: 3) Hezbollah in Yemen, fantasising about some 'increased tempo of Iranian arms deliveries to the Houthis', and increasing the resulting hysteria for an 'Iranian effort to destabilize the Middle East'.

...while two (out of several thousands) of videos showing a few Iranian protesters calling for something like 'return of the Shah', are happily misinterpreted into who-knows-what sorts of amazing stuff and whatever else.

When not only the politics, but indeed the entire 'reality' goes that absurd... then it's sure as Hell: there few billions of sticky, little, green truths in it.
