No one ever said that they could co-ordinate 18'000 attacks simultaneously. No one's worried about that.
What we are worried about is that they'll try, miss, and hit 100 random non-targets instead.
On a very different side of things, Sony's doing the right thing. As an entertainment company, indeed as any consumer/commercial company, Sony should not be creating a war -- rightfully or not. If it gets to that level, as it just did, Sony ought to back off and your government ought to step in to do something -- I know exactly what my country would do: publicly apologize for the insulting movie, as a sign of respect, and move on.
But your country doesn't like $50 solutions. Your country has always preferred $50 billion dollar solutions. So your president will likely escalate matters with a display of power. And if things do escalate, as we all know that they have in the past, you'll lose a few thousand soldiers' lives, instead of a few thousand movie-goers' lives -- as though that's somehow better, or any different at all.
Of course I'm all for freedom of expression. Of course I'm against slander too. And maybe, just maybe, it's a bad idea to insult an enemy while he's holding a few nuclear guns. Just maybe.
But hey, your country fought for its independence, with a lot of lives lost. Mine waited 100 years, and then asked politely.
