Why always Iraq but never Afghanistan?

John Payne has quoted from Wikipedia, "A strong supporter of the Blair government, he supported the 2003 invasion of Iraq,[7]"

Am I alone in thinking that so many, rightly, condemn the Labour Party for attacking and invading Iraq but seem to excuse or even agree with the attack on, and invasion of, Afghanistan that began the War/Crusade of (not 'on', in my opinion) Terrorism on the 7 October 2001?

Afghanistan then got it in the neck from us upright, peace loving and law abiding Westerners for the next 13 years (to Dec 2014).  All this slaughter as revenge and punishment for having Al Qaeda in the country, who launched the 11 September 2001 attacks in New York.

Am I completely off beam in thinking like this?
