Do you know that George Washington and Alexander Hamilton conspired to make Washington king, but the letter (which still exists and can be read online) wasn't made public until long after the Constitutional convention where the anti-federalists refused to allow any king making? Google it and find out just how close we came to a monarchy with Washington made executive for life. He was politic enough to pretend it wasn't his idea when the vote went against it, but it's available to research anytime you want.

So, yes, Washington was indeed a traitor to the cause of liberty. I admire the US Constitution as the best in the world today, but the fact is that we gave up liberty when we replaced the Articles of Confederation, which actually would have worked if they'd amended it (which required concurrence of all the states) instead of replacing it with a document that would eventually lead to our current tyranny of some states dictating to other states.
