Yes, but we didn't do any of this because they were Muslim, it just so happened that they were Muslim.
I presume when you say 'we' in this context you mean Britain?
Well, Blair was persuaded to drag Britain along with the US. He said at the time it was because of the threat Saddam posed, links to Al Qaeda, WMD's etc, all lies as we now know, but later he admitted it was 'because of 9/11'.
Either way, he was fooled by Bush and those who were behind the plan: the Neocons, AIPAC, many prominent right-wing Republicans and the top-dogs of the military industrial complex, all of whom convinced George Bush to give the green light, which he probably didn't need much pushing to do, given daddy didn't complete the job.
And a long-term plan it was too. The same people who created and orchestrated it also drew up plans to change the regime in Syria by using Islamic extremists as proxies. They also planned regime change for Libya. All of these goals have been realised, Syria to the letter, though obviously not fully as Assad is still hanging on.
The last part of the plan is Iran, and I don't think anyone needs telling who wants them attacked.
All Muslim countries, yes, but all Muslim countries with leaders who were/are independent of the US, and considered as an obstacle to US/Israeli hegemony, and a threat to Israel.
Saudi Arabia isn't. Egypt isn't. Jordan isn't, and none were targeted even though they are all Muslim countries.
So you're right. It isn't a Muslim thing, it's an obedience thing.
