Now now, lets not go all reefer madness on the lowsec thing. You just need to be careful, and know the mechanics. Certainly you shouldn't fly through a lowsec entrance unprepared, and not if you have no particular reason for being in lowsec.
As for a war, all a war is in the formal mechanical terms is paying for the right to kill members of a given corporation anywhere without reprisal. Lowsec pirates happily ganking anyone who jumps into lisbaetaenne unprepared aren't likely to bother with a formal declaration of war. They're just out for targets of opportunity. Now it may well be that they live in the area and regularly camp that entry point. The truth though about most pirates is that they're pretty lazy, and just want easy, uncontested kills. Be informed, fitted, and prepared enough not to fall into that category and you should be fine.
Oh, and if you get podded in lowsec, you either got really unlucky or messed up pretty bad; which is okay, just another wrinkle of the mechanics that you need to be briefed on. Specifically, pods align for warp basically instantaneously; if you take proper advantage of that fact, opponents shouldn't really have a chance to lock down your pod to kill it in lowsec (the rules are different in 0.0). If you are in a fight that you know you can't win, have a planet, asteroid belt, or other celestial selected before you ship goes down; as soon as it does immediately hit the warp button on the options under your selected celestial and you'll be off to safety. Some well put together camps are set up specifically for near instant lock ons, so those might catch you, and then there's smartbombing battleships that just spam area of effect damage which will nuke your pod without requiring a lock. Aside from those instances your pod should be pretty much safe in lowsec.
