In a recent social post, Trump said: "We will be taking Kharg Island and other oil infrastructure points, and assume total control of their [Iran's] Oil and Gas Markets, much like we have done with Venezuela."  And he is also going to steal Greenland and Cuba, because America needs, or deserves, to have them.  

The current US national debt is almost $40 trillion.  This is a bit more than $114,900 for every person in America, working or not working.  This is an amazing debt for Americans forty percent of whom the Federal Reserve says are incapable of covering a check for $400.

Foreign central banks hold about one-third of US national debt as represented by US Treasury bonds.  As US Treasuries serve as the reserves of the world's central banks, US deficits have not been a problem to finance as US debt instruments denominated in US dollars serve as the underpinnings of the world's banking system.

For a number of years Washington has been working to undermine this support for the US dollar with its aggressive sanctions against other countries. Any foreign central bank that keeps its reserves in US dollars can lose them to American sanctions.

A policy of sanctions makes no sense for a country whose currency serves as the principle world reserve currency, especially a country whose ability to finance its debt is dependent on the willingness of foreign central banks to hold its debt. In other words, US policymakers are stupid beyond belief.

It is not only the dollar's value and the market for US debt that face challenges.  The Social Security Administration reports that the retirement trust fund will have exhausted its reserves by 1932.  That is six years from now.  

This does not mean that Social Security Retirement will have no money.  It will still have the annual payroll tax revenues, but the revenues will only cover about 77% of the current level of benefits. So, either the payroll tax on working Americans will have to go up, or the retirement benefits will have to be cut.
