Imagine the following scenario:
Syria hosts a groups which has just assassinated a high-ranking Israeli elected official. Israel is threatening immediate military action against Syria, unless the group is arrested and turned over to Israeli authorities for trial and punishment. The leaders of France and Germany plead for calm, denouncing in advance any "reckless" U.S. action. England says terrorists must not be tolerated.
If this were to happen in, say, March of April of next year, we all know pretty well what President Bush would do about it ( And to my mind, that's one reason nothing like that has happened there ).
But if John Kerry were to be the President in such a situation, how would he handle it? When you understand, you'll know why it's so important, for so many reasons on so many levels, why President Bush must be re-elected.
