There are many things which I agreed with in your post Bernie, but the above is not one of them. You are using the exact words which Tony Blair did at the time, when following our intervention in Afghanistan and Iraq, there were bombings across Europe, in India and in Asia. I am afraid that you cannot ignore the simple law of action and reaction.
Prior to 9/11, the US had been attacked mainly in the Middle East/Africa by Al Qaeda, who cited US interventionism as the reason.
Can you please tell me how many Islamic terrorist bombings took place in Europe prior to our invasions of Afghanistan and Iraq?
When we invaded Iraq, we destroyed the infrastructure of the country, we had no plan for the future, we disbanded the Iraqi army and we created a void which was filled by extremist factions who set about killing veryone who disagreed with them. Saddam was a horrible dictator, but he had nothing to do with 9/11, and his country is now in a far worse state than it was when he was in power.
In the past 15 years, the US (backed by the West), has been influential in regime change in Afghanistan, Iraq, Libya, Egypt, and has attempted regime change in Syria which has helped IS expand into Iraq.
