As long as i get to be the frog
I don't think that would represent a combat as war style action. Maybe the night after their first successful adventure thoughIf the DM adopted a "RPGs as war" approach, sure. The toughest boss in the campaign would just burn down the tavern the 1st level PCs were sleeping on night 1 of the campaign.
NPC's don't have to be omniscient. They can get information about the PC's the same ways the PC's do about them. One of the oldest strategies in the book would be to turn the promising young adventurer into your ally and if they don't then ensure they cannot oppose you. This doesn't have to happen instantly. Things like this don't have to happen instantly, and that's why I was careful to use the word 'eventually'But the NPC's aren't omniscient. The big bad does not realize those meddling kids are going to uber powerful heroes who will be his biggest threat in the near future, and he has lots of other, more pressing things to worry about.
Bringing up countries into a game that's about a team of individuals seems a little off. I've seen this done a few times and this is just the latest example - but it's not at all informative.Actual war tells us that commanders make flawed decisions all the time (Hitler invading Russia), and bad luck can mitigate even the best decisions (the US aircraft carriers being away from Pearl Harbor at the time of the attack). The DM can usually set up the stage in a plausible way so that the PCs have a reasonable chance of success, even if the enemies within that scenario are fighting to the very best of their abilities.
Also, if the DM is looking to set things up in a plausible way so that the PCs have a reasonable chance of success then he's actively stacking the deck against team monster. From a combat as war perspective that idea seems strange.
