Who were the "Western Christian nations" bombing on Tuesday, September 11th, 2001?
Are you suggesting that because the US wasn't bombing anyone at the exact time 9/11 happened this somehow overrides the exhaustive list of US intervention (resulting in innocent muslim deaths) over the past 2-3 decades ?
Did you know that UNICEF estimate over 500,000 Iraqi children have died due to UN sanctions since 1990. Even the most conservative estimates have it in the 200,000 range.
There is a famous interview with Madeline Albright (then US Ambassador to the UN) where she is asked about the estimated half a million children who have died because of the sanctions and her response was "this is a very hard choice, but we think the price is worth it"...
Let that sink in. 500,000... and that's not even including the deaths from the wars !!! It should also give you an idea of the level of apathy the western governments have towards innocent Muslims dying.
Like it or not Muslim extremists have a verrrrrrrrry long list of legit examples of the west screwing Muslims, they then use these examples to try and justify their atrocities.
