There was no war in Iraq no Shias killing Sunnis or vice versa until after the USA invaded, raped women, killed kids and sowed the seeds of emnity between people.
As for Afghan the Taliban had a war with the northern alliance no high tech bombs or drones.
Just Google how many civilians the Americans killed in Afghan and Pak area also due to drones and air strikes. Started a insurgency in Pakistan that killed 70,000 Pakistanis.
And in the end walked out of Afghanistan with there heads in shame, say thank you to Pakistan.
Warned them that they will come and go and Pakistan will have to deal with the **** they caused and that's what happened.
And what air strikes and drone strikes and mass murders are happening now in Afghan and Iraq, isolated incidents but nothing like the **** the Americans and it's allies did.
