Folks, China and Russia are itching to get at us. The Chinese want world domination and will start some major beef soon. WWI and WWII are not that far away and this time around there won't be a Pearl Harbor, the Chinese as well as the Russians will send intercontinental ballistic missiles loaded with God knows what. If you wait until "point of no return" it's good night. Be proactive, when hostilities start (trade agreements being cancelled out of the blue, one of the said countries asking the other to vacate x military base, etc) MOVE.
WWII was 9 years in the making. WWIII will be a a tenth of that, meaning 1-2 years before it starts "raining". Once China says "fuck you and your trade agreement," immediately do this: 1) find a business partner in NZ, 2) get a investment visa for you and your family, 3) take a sabbatical, 4) relocate to NZ for 1-3 years, 5) open up a coffee shop with your NZ partner and 6) pay taxes in NZ. Don't worry, the laws are such that once you open up the business they will want to keep you there.
IF, after the 1ST year the hostilities ramp up, sell everything in the US and wait it out. If nothing happens you can always come back. If shit hits the fan, pat yourself in the back, you've survived. 99% of all you know will be gone but you made it.
