Good questions, Jay. Consider the case of Vietnam. Over the course of a few decades the French and Americans killed millions of Vietnamese - combatants and non-combatants alike. Their country was destroyed, jungles deforested. They have every reason to hate us and want to exact revenge. But do we see Vietnamese terrorists plotting to destroy our country? Do they have protects where they burn our flag and chanting "America is Satan"? If we printed some cartoons mocking their country, people, government and way of life, would they seek to kill the authors and publishers of said cartoons. It seems there's more to it in the case of those in middle eastern countries who want us destroyed - including countries we have never invaded, nor in which we have killed millions. I wonder, just what the difference could be...
