So it seems to me that this is one possible, most likely scenario.
In about 4 years the voting system in this country will touch off a civil war. (Or at the very least the civil disobedience of many.) Because people will be divided about who should have power to do things, nothing will be done. When our foreign obligations become lax and we cannot hold up our end of an agreement, (in the far and mid east) they will see that as opportunity to move in on this country. They will feel that they have the right. This is going to take about 10 years for people to get angry enough to do something with more impact. During that 10-year period there will be groups (like organized crime) that will see the division of the people as an opportunity to get rich and/or get power. This will help the in those who seek to hurt this country. By the time we realize what is coming it is already too late, having been distracted by our own civil war and others with in who sought control. Basically we weren’t looking and got hit.
Doses this seem close? It has been the pattern for other countries in the past.
