You guys staying in the western hemisphere need not worry that much, Portugal, Sweden, Denmark etc .... I stay in Malaysia, a Muslim country where i dunno what can i do if the US suddenly sent a Nimitz class carrier and claim that we're developing nuclear weapons, then bomb us...
although i know its quite impossible... (hopefully) as these things wouldn't have cross my mind when i watch Beyond 2000 back in the 80s and dreaming life in y2k would be a peace, war-less world, with no famine, cure for HIV.... however.... things ain't so optimistic as it seems, youngsters in Iraq who watched Armageddon and drink Pepsi under Saddams reign never have thought of how their country ended up as well....
It seems and sounds absurd when a kid in the 21st century could at the same time play PS2, and was slaughtered the next day. But hell, it happened. What wouldn't?
