If you don’t want to read the massive investment thread (although it would probably be a good idea), the first requirement is for you to define your requirements. What do you want to accomplish with your money? If you have certain ethical/moral requirements, what are they?
Once you have done that you can make a plan for investing.
Then just follow the plan. Don’t allow day-to-day news or even your hunches about long-term trends to knock you off your plan.
If you have a fear that the government will somehow freeze your assets then you probably shouldn’t be invested with US-based companies at all (which would be every IRA, AFAIK). Gold under a mattress is probably the only option at that point.
