Who thinks that an army is unnecessary?

I received a draft notice from the military recruitment office the other day. Now I need to figure out how to avoid it. This made me think about creating a poll: does anyone really need an army? Personally, I think that all the world's armies should be disbanded long ago, leaving only some kind of squad to fight terrorism, crime, and aliens, and a world government should be created. What do others think about this?

If we don't consider true warriors and defenders, then in Russia, the army is only needed by those who have nothing else to do. After all, they provide you with clothes, food, and housing (barracks). And you don't have to do much. They do mess with your head, but amoebas don't need a brain.
In general, the best option would be to switch the entire army to a contract basis, but the government simply doesn't have the money for it. But in general, a professional army is definitely needed. A strong army is an additional source of a country's authority in the world.
