Hi Eagle3,
Overlooking a trigger is a possibility--I've done it before...and am not entirely sure I stopped...

As for prepering for "eventuality"...I always want to have candles/flashlights, canned food etc around in case another war starts and have my passport near me at all times...so that if it did start, I could split ...I also watch news obsesively (so as not to miss poetential trouble) even though I get triggered...
