Absolutely agree with meghatronic, as I stated earlier, there is only one insurgency that has potentially been defeated by force alone - the Tamil Tigers in Sri Lanka.
Usually a combination of force and diplomacy has been the long-term solution, and that's what we're starting to see now. Look at Ireland for a recent example.
The Tamil Tigers were a separatist movement not an Insurgency, the main criticism of the tactics used in defeating the Tamils include Summary Execution of political opponents, Torture, Mutilation, forced expulsion of large sections of the Tamil community, Allegations from the survivors of The Mullaitivu "no-fire" zone, who say that Govt forces bombed them after the declaration of the "no fire" zone causing the death of over 20,000 Tamil civilians and allegations of genocide.
It is allegations and actions like the ones above that validate the conditions set in the GC and International Law, and the reason why we follow them despite the fact that the opponent does not always abide by the same moral and legal codes.
Sri Lanka is subject to War-Crime investigations by the UN, and has been criticised by the UN and other groups for a failure to investigate the allegations made against them. (Gen Fonseka's conviction on corruption charges notwithstanding.)
You only need to look at the Bosnian War to see what happens when opposing Forces do not abide by RofE or the GC and resort to Total War.
Do those of you, namely Amnesia and Nickg think that allowing the same or similar tactics to be used in theatres such as Iraq and Afghanistan would help the situation at all?
I can assure you that it would not, all it would accomplish is a breakdown of what law and order there is, which in turn would lead to massive loss of live among the civilian popualtions, enforced diaspora's of minorty populations, genocide of civilian groups, widespread ethnic cleansing and lawlessness.
Both the Iraq War and the War in Afghanistan are two fold, first was the removal of a brutal regime which was a threat to it's own civilian population and international security (be it military or economic), in both cases this aspect of the operation was accomplished successfully. The second and far more difficult part of the mission parameter is to restore order and a rule of law until a democratic government is in place and capable to assume responsibility of it's own security. In Iraq this is finally coming to fruition, although there is a long way to go because of the external insurgencies which blight the region.
Afghanistan is different because the external insurgency is supporting an internal militia and you have the added problem that the Pashtun peoples are widespread throughout Afghanistan, Pakistan, Tajikistan and other neighbouring countries so that added to the terrain adds to the difficulties politically and militarily in engaging the enemy effectively.
The main weapon in combatting these difficulties is winning the support of the Pashtun people, this cannot be done if we engage using the tactics of terror and total war, they will simply see us as invaders and foreign occupiers instead of people who are attempting to restore a free and lawful society. We must lead by example and not lose the war simply to win the battle.
I find it curious that those who argue that we should not be in Iraq or Afghanistan then complain when we do not use military force against Somalia and Zimbabwee which would have similar (probably worse considering Rwanda and Congo) consequences. Make your mind up, do we or not.
