Tiananmen Square protests were squashed by the Chinese military but the Russian military refused to shoot their compatriots and walked off the job. Military intervention got the Serbians out of Kosovo but didn't keep the NVA out of South Vietnam. What works in one case doesn't work in another.

Please try to tailor your propaganda to the arguments made on this board. Few here have opposed the intervention in Afghanistan. Your messages are like angry spam and it's annoying.
