Given the number of really bad policies that various US governments and officials, from school boards to POTUS, have implemented, especially recently, it is high time to restore weakened or lost Constitutional restraints against arbitrary rule.
Five forces threaten Americans with destruction:
2) foreign powers;
3) the national government;
4) state and local governments;
The threat from 3, 4, and 5 is double-edged, meaning that Americans can be harmed by the actions of those forces as well as by their inaction.
The national government, for example, can harm Americans by being insufficiently prepared for natural catastrophes and foreign incursions, as with Hurricanes Katrina and Rita and the 9/11 attacks. It can also harm Americans, though, by doing too much, as with the invasion of Iraq and the way-too-long occupation of Afghanistan. (Relying too much on FEMA instead of states or private initiatives may be another example, but less clear cut than the needless wars.)
