Should we let Europe burn this time?

One would have to be blind to miss the decline of the West.
The USA is becoming more isolationist by the month. Economies shrink globally.
Export markets have shrivelled and imports and debt have become our stock of trade.
In the midst of this, like some flock of mad ostriches, the governments bury their heads in the sand and pray nto some mythical future technology or event that will 'save us'.
The USA, Australia, Canada, and New Zealand watch in horror as the UK and their new masters in Europe plummet into chaos. Seasonal riots, immigrant revolts, Islamic intifada: ALL in the EU. Some leaders seem to recognize this and call for change and a REVERSAL in policy, but will it come?
For the purposes of this post I will assume it is NOT coming.  I will assume that the Federal powers of the EU are engaged in social engineering and have NO intention of preserving indigenous European culture and values. I hope I am wrong here, and I may be.... but IF I am not, should we in the Americas and Australasia run to help, AGAIN?
Us backwards ignorant 'red-necks', 'bible bumpers', 'hood rats', 'cowboys', 'eskimos', and 'arrogant' North Americans in general  have done it before, and could no doubt do it again, but at what cost? Millions of lives? Generations of our youth?
As contradictory as it sounds: YES, we should. Why? We are next.
Europe has been deracinated by socialist (national) policy. A vacuum has been created and it is now filling RAPIDLY with 'others' that will soon enough wrestle for control.
Quite simply put, if we allow this to happen there  - it will happen here too. Europe and our ties with her, will be used as the staging ground.
Should we let Europe burn this time?
For altruism: NO. For pragmatism: NO!
We must NOT let Europe burn again, even if that means preventing it with FORCE.
If we do allow the downfall, it will be at our own peril.
