These tweets are pretext for invasion by US forces - and the start of WW4 minutes after that.

WW4? What happened to WW3?

There won't be WW3 or WW4, but Trump will attack Iran. Russia and China won't go to war with USA over Iran. Not today, not tomorrow, not ever.

The price of oil will skyrocket when Trump attacks Iran and given that Russia is a major oil/gas exporter - they won't complain much. In fact, they'll work on prolonging the conflict by giving as much support to Iran as they can without going head to head with USA.
