I must say, it is really funny to see so many Americans actually having the gall to declare out loud and in public that the reason they don't like this law is because it will open up America to having to be accountable for all the terror they have brought on the world through their defense, security and intelligence forces. It is the same reason why they justify themselves not becoming a signatory of the ICC.
Now Americans not wanting to be held accountable for their crimes (or Americans not wanting their government to be held accountable for their governments crimes) would be nothing unusual if it wasn't for how quick they or their government is to bomb the hell out of supposed tyrants and dictators around world. And the excuse used for their governments terror attacks is often that these "evil men" are killing their own people. Now isn't it ironic that America should be so keen to bring justice against foreign leaders who kill their own people but is so reticent to bring justice to a foreign government who may have been involved in killing the American people?
The truth is that, internationally speaking, America is a criminal state and a bully. But I rest in the knowledge that no empire lasts forever.
