Based on our experience in Iraq? Lol. Iraq was badly beaten, weakened, with no military power, and took us almost 9 years to accomplish nothing except 1 trillion dollar spending, +4,500 American dead criticizes, +50,000 mentally and physically maimed individuals, and almost 1 million dead Iraqis. Now, your assessment is 3 weeks for neutralizing Iran which is 4 times the size and population and 100 times more capable militarily and technologically? What have you been smoking?
