It's more the wrong question because the "international community" as such broadly supported action in Afghanistan and (to a lesser extent) Iraq. Lots of individual groups had qualms, but none rose to the level of actual policymaking in democratic governments. Obviously in hindsight (informed by the results of the occupation and the exposure of the extremely spun intelligence that was used to justify the war) lots of people would claim to have "opposed" the Iraq war, but at the time it was mostly just shrugs and silence.
