In the first case you cite, you’ve misidentified your enemy. You’re not fighting the nation, you’re fighting some subset of it. The usual response is to identify a significant subset that opposes your enemy subset and supply them weapons. Be careful—a lot of Afghan anti-American insurgents started out as a US funded anti-Soviet insurgents. The enemy of your enemy often stops being your friend when your first enemy has fled.
For the second case—the enemy is probably not stupid or politically naive (they’re leading a country, after all). Anyone within their borders who impedes their prosecution of a war will very likely be imprisoned and replaced (and probably executed). You may see the occasional Oskar Schindler type who’s willing to take the risk and cunning enough to carry it off, but that’s pretty rare and it’s far too slim a reed to support a realistic military strategy.
