No we did the opposite, i would've been against meddling, your hero Reagan supported and armed Osama and friends. Look where that got us.
And no Afghanistan never had anything close to a stable gov't, and Iraq has always been run by a dear friend to Iran and Hezbollah and the gov't itself is based on Islam.
You are honestly trying to compare circumstances from the 1980s with today? Really?
We went in and helped the Muj kick out the Soviets. Then we left them alone and the taliban took over, precisely because we weren't around. They still didnt trust us. Neither did the people in Basra and damned near the Kurds because we did exactly wht you suggest: go in, break stuff, and leave. It is a failed policy.
Iraq has always been run by a dear friend of Iran? Really? Are you totally ignorant or merely stupid?
