There is nothing isolationist about peaceful trade and travel. Nothing. Get it right.
Sorry for the intrusion. You may all now resume squabbling over which leg of The State gets to stand on your neck.
Trade and travel is also dependent on security, good order at sea, and low energy prices. Countries with highly dynamic economies being threatened with SRBMs and IRBMs by tinpot dictators (South Korea, Japan, et al), the risk of chokepoints being mined and/or blockaded (the Strait of Hormuz), and pirates running roughshod over the SLOCs (Strait of Malacca and the Gulf of Aden) aren't exactly conducive to this. For those who think they can live with that, then I hope they enjoy their new $75,000 Hondas (that contrary to vehicles built by domestic manufacturers for many countries, you can count on to _work_), $10,000 Samsung TVs, and gas at $10 a gallon.
