war and poverty

According to the Telegraph online today a further 1700 British troops are to be deployed to Afghanistan very soon.
Now, I will say at this point that I was against the war from the outset. I am not for one second saying that the regimes in Afghanistan and also Iraq were good, quite the opposite, the atrocities carried out by the Taliban and by Saddam Hussein were utterly appalling but the actual reasons we went to war were not acceptable, and were under false pretences. We were told there were WMD's in Iraq - it has now come to light that our government had good intelligence to suggest this was not true. The war against Afghanistan was not started because the US and the UK were so aghast at the Taliban regime, which had been going on long before the 9/11 terrorist attacks but as a knee jerk response to the atrocities carried out on American soil. It is known that a large part of the Taliban is Pakistani based and Pakistan also have nuclear capabilities, but because the US has some kind of alliance with Pakistan no action is taken against them. Similarly North Korea has a terrible regime run by the crazy dictator Kim Jong-Il, and has repeatedly claimed to have nuclear power, yet so far no action has been taken. Saudi Arabia runs a totalitarian regime based around Wahhabism and sharia law which sees women being executed for "crimes" such as speaking to a man who is not their husband, or accidentally showing a flash of flesh in the 40 degree heat. Yet because the US and UK are "friends" with the Saudis again no action is taken. And of course the recent situation in Zimbabwe has seen western leaders turn a blind eye.
So while I don't agree with these kind of regimes I don't think the reasons for going to war with Afghanistan and Iraq were justified. Maybe when there are no more problems in our own country, no more homelessness, no more pensioners dying because they can't afford to put the heating on, when child abuse and forced marriages are a thing of the past maybe then we can set out and try and "liberate" other countries.
As it stands at present though our government are literally pouring millions of pounds into bombing the hell out of countries thousands of miles away, and seeing our troops being killed in their hundreds while at the same time the country is in recession and the government is having to borrow money from the IMF. Surely the common sense approach would be to withdraw our troops and spend the money on trying to sort out some of our own problems. Because I don't think we are far from seeing some serious dissent here in the UK.
