Two years is too long.
Recommended course of action:
1. BLOAT
2. If you are in or downwind of a major urban area, move as soon as possible to a safer location
3. Dig in with a defensible perimeter
4. Be ready for TSTHTF
5. Once TSTHTF, aim small, miss small
Unfortunately, after two whole years of Democrat appeasing and dissembling, that may be our only defense.
