Let me ask a question, was Irán a thread or Russia?.
Russia was able to reach at least Kiev in some weeks.
And worse all. Russia (thanks to Biden support) lost probably tens of thousands of troops not to mention hundreds (if not thousands) of armored vehicles.
Irán did not have neither serious Air Force, Navy or even Army to invade nobody.
Let's be honest, Trump was Putin's silver bullet to stop Pentagon and NATO Unity.
And the most probably outcome It is still to unveil. A NATO proof Russia hardened conventional Army at the North and Iranian nuclear powered country at the South of Asia.
And Biden did It... WTF!.
