It is important to realize, leaving the Iran Agreement was a CAMPAIGN promise. Trump's actions are all based in hate. Just that simple.

The tensions that exist today is a direct result of Trump's willingness to escalate ANY situation; ie: the USA Southern Border. 

There is no REAL REASON for any of Trump's actions regarding Iran.

Putin, the Russian president with two nuclear capacity jets in Venezuela, is stating any relationship with the USA is deteriorating BY THE HOUR. (click here) That means Trump no longer serves Putin's purpose as a populous figure in Russia.

Trump fell right into the trap.

He shared high valued classified information the day after James Comey was fired. He held a private meeting with Putin in Helsinki that went on for hours. He has made Russia a priority in many public statements. He is the fool Putin longed for and put him in the presidency to benefit Russia.
