Iran's military backed Islamic theocracy is evil. A threat to Israel. A threat to world peace as proxy to China and Russia.A threat to stability of the world's oil based economy through their ability to close the Straits. Reasons enough to go to war with Iran if the goal is to eliminate that threat. If the war results in the status quo of February 27th, it will not be defeat for the US but opportunity lost to effect positive change for the world.
In my opinion the opportunity was lost very early on when it became evident the US either had no plans or willingness to seize the Straits of Hormuz and the Persian Gulf. Leaving the weapon of economic blackmail available to the Regime. End result stalemate.
I do pray any deal that Trump reaches is effective and results in peace on our terms in the Mid East. Yet given Iran's prewar behavior, I will not wager on a deal lasting.
I am of the mind that war should be rare,
