Well, we wouldn't need to develop special vehicles to use at our ports to protect against IEDs (snip) we wouldn't have to spend the money we are doing on helicopters
Yea, but how much money is that in the grand scheme of things, to anyone here it's colossal, but as part of a military budget spread over 5-10 years (how long these vehicles should last).
It's peanuts.
flying the troops out the and back, even feeding them whilst they are at home if the sensationalising press are to be believed.
Peanuts.
We did manage to train our troops before we went out there
You do know that since WW2 ended we have been in one small war or another almost constantly.

India, Palestine, Malaya, Korea, Suez Canal Zone, Kenya, Cyprus, Suez 1956, Borneo, Vietnam, Aden, Radfan, Oman, Dhofar,
Northern Ireland, the
Falklands War, the
Gulf War, Bosnia, Kosovo, Sierra Leone, Iraq and many more.

As for your point on troops knowing what they're getting into, that's a perpetual argument which won't go away, but fighting for "Queen and Country" and laying down your life in that pursuit is hardly relevant in that war.
As above, as a country we have been sending troops to fight in foreign parts nearly every year since WW2 ended.
Anyone who joins the army thinking they won't end up seeing action in some backwater country is either ignorant, deluded, or just hopeful that they can take the pay check, but it won't be them getting sent.
Again, I don't think we should be in the stan, but from a military perspective, and looking at the costs, It could be argued to be beneficial.
