The U.K. and US have had similar allegations of war crimes, but when you have an enemy who are killing and maiming your mates with sniper fire and IEDs you are going to get angry troops with battle stress and post traumatic disorders sent out next day to face the same risks. It’s easy for us sitting at home to criticize, my brother in law was a squaddie in Ireland, he came back with real problems, the only solution is not to get involved in this type of war.
The West should never have got involved in these Arab and Afghan wars, the leaders were despotic certainly, remove them and you have either chaos or a guerilla war, dont we ever learn from history Britain fought 3 Afghan wars, won one by bribery, lost two, the Russians lost theirs, the current war was lost years ago.
I particularly criticize the US for their mindset that every country should be democratic on the US model, it doesn’t work and they have lost every conflict since WW2. That’s not to say that eliminating Bin Laden was not justified, go in bomb the hell out of him then go home, job done.
