When at first you don't succeed, try, try again.
Do you think that the American Revolution worked out smoothly, with no slip-ups, no enemy victories, no casualties? The obvious answer is "no" - but that didn't prevent the Founding Generation from regrouping, licking its collective wounds and trying again and again until the Brits tired of fighting us and left.
To those on this thread who think that the fact that so many are dependent upon and supportive of the feds means an automatic defeat: think again. First off, if they're so dependent, then by definition they're sheep. Second, the American Revolution was not supported by all of the people - roughly 1/3 of the population were Loyalists and not only didn't help, but actively hindered the Revolution and cooperated with the British tyrants...and yet it is they who left for Canada or England when the bullets stopped flying. It is good to be aware of and realistic about what resources your enemy has at his disposal, but it is unwise to think that there is no way to defeat Leviathan...just ask the cave-dwellers in Afghanistan, who have defeated the 2 most powerful empires known to human history in a single generation.
The Afghans didn’t defeat the Brits. The Brits eventually imposed their will and put an end their raiding for duration of the British Raj.
We can’t beat them because we’re not ruthless enough. If we applied the methods of the British Raj or, better yet, the Mongols, we could get this over with and go home secure in a real victory.
Of course, there wouldn’t be very many Afghanis left...
You have a typo. It's supposed to be "If at first you don't secede...." ;)
