They quickly went and signed a defense agreement. Saudi Arabia after helping the U.S. in the war kill Iranians they are now scared about repercussions. Same shit they did with helping Saddam .
And since Pakistan didn’t fight Iran on their behalf, they are now dragging Turkey into this.
Who else are they trying to protect themselves from? Saudi Arabia and Pakistan aren’t going to fight Israel, if Israel and Turkey get into a war. And Saudi Arabia and Turkey won’t fight India if Pakistan gets into a war.
So the logical conclusion is this is a united front against Iran.
