Idiots will out.
America was no longer just the place to send the village rebel.
That's when the problems really got started ~ with England, with France, with the German states, with Austria-Hungria, with Russia, with...... the A-Rabs!
it's not like we'd been working along in splendid isolation from the world. My gosh, George Washington was part of the cause of the French and Indian War. The War of Spanish Succession certainly had something to do with American economic might behind the Brits! And, even earlier King Philippe II/III of Spain had used the division of North America as a ploy to bring a full 20 years of peace to Europe ~ (See Treaty of London 1604 ~ it's not about England winning a war ~ it's about Spain winning a war and being magnanimous ~ incredibly magnanimous).
Ron Paul's idea of cause and effect is very similar to the theory of a suppository. That is, that if you keep sticking it up your nether regions it may make its way to the top.
