My country accept them cause Europe says so and Europe most possibly because that way we can have some more terrorism. I bet all that is because they want to spy on us bit more, just like USA does to their citizens. I really cant imagine other reason.
How about money? That thing that seems uppermost in the minds of most people? Imagine that. War, weapons sales? It seems kind of likely that weapons manufacturers are interested in the weapons being used. It´s a business. Usually businessmen are interested in repeat sales at least they´re more interested in that than going out of business because the market has dried up. And I think we can safely assume that management and shareholders are very interested in the share prices.
