I know I’ll get branded as a Putin apologist, again; but, what’s your historical evidence for this statement?
An Iran War Would Destroy the United States – Jul 30, 2018 - Philip Giraldi - ahtribune
Given the size of Iran, its large population, and clear intention to resist any U.S. attack, military action against the country, which many in Washington now see as inevitable, would be by missiles and bombs from the air and sea. But it would not be a cakewalk. In the past year, Iran has deployed the effective Russian made SA-20c SAM mobile air defense units as well as the S-300 VM missile system, which together have a range of more than 100 miles that could cover the entire Persian Gulf. Radar has also been upgraded. They are the centerpieces of an air defense system that could prove formidable against attacking U.S. aircraft and incoming missiles while ballistic missiles in large numbers in the Iranian arsenal could cause major damage to U.S. bases, Israel, the Gulf States and Saudi Arabia.
All of which means that Americans will die in a war with Iran, possibly in substantial numbers, and the threat by Iran to close the strategic Strait of Hormuz is no fantasy. It has threatened to do so if its own oil exports are blocked after November 4th, even if there is no war. And if there was war, even if subjected to sustained attack, Iran would be able to threaten ships trying to use the Strait with its numerous batteries of anti-ship missiles hidden along the country’s rough and mountainous coastline, to include the Russian made SS-N-22 Sunburn, which is the fastest and most effective ship killing missile in anyone’s arsenal. Fired in volleys, it would be able to overwhelm the defenses of U.S. warships, to include aircraft carriers, if they get too close. With the Strait closed in either scenario, oil prices would go up dramatically, damaging the economies of all the major industrialized nations, including the United States. A major war would also add trillions to the national debt.
Iran also has other resources to strike back, including cadres ready and able to carry out attacks in the United States and Western Europe. The reality is that the United States has no motive to go to war with Iran based on its own national interests but seems to be prepared to do so anywayunder pressure from Israel and Saudi Arabia. If it does do so, Iran will certainly lose, but the damage to the United States at every level might possibly be very high.
