Of course it is treason, but treason is fun, just the thing, everybody is doing it these days. Of course they will pull the plug and therefore Iraq will be lost and abandoned to chaos and death and Iranian power grabs. They know it, they do not care. They will blame it all on George Bush and just say "we told you so, we should never be involved in anything in the middle east, it never works".
They haven't yet realized that even defeat will not be accepted by the enemy. That it will be the merest begining of the string of humiliations reserved for them. But as soon as some sane man points this out and infringes their sacred political power again, they will have a new black beast to blame for all of it, and will happily revert to doing so.
