[The Punisher] Why doesn't Frank Castle use his vigilante skills to topple oppressive regimes and dictatorships?

I was thinking about the logic behind the Punisher's actions - he goes around killing criminals because he believes that this is the only way to "get the job done" and clean up the streets. Ok, fine, his morals are fairly "flexible" to not call him outright ruthless and psychotic and the man himself is implied to have lost part of his sanity a long time ago back when his family was killed. But if left me thinking. If Frank truly wants to fight crime and "human scum"... why doesn't he go to oppressive countries and liberate them using his peak human abilities?

While the comics world is obviously different from ours - i doubt it also doesn't contain countries with dictatorships and innocent people being killed and arrested. North Korea, Syria, Saudi Arabia - all of them have governments infamous for their arrests of journalists and protestors fighting against their regimes who body counts are probably in the hundreds of thousands right now, and yet Frank would ratter go around killing muggers and serial killers than doing something about them with his big guns, even though his entirephilosophy is based around punishing the wicked and those who would hurt the innocent. Why?

And just to leave this clear - i know some people are going to say that fighting against an entire army is different from murdering criminals - and i admit it is. But..... Frank is also no common hired gun, he has fought against entire criminal organizations before on the same level of The Zetas in Mexico, if not even stronger and more resourceful. Even if he alone can't take on the government of these countries, he could join a rebel or insurgent group and act as a special forces fighter for them, going on one man missions in strategic locations to give them the edge necessary to topple the regimes. And it's *Frank* we are talking about*,* it's not like he can't take on a army base with some preparations beforehand.

Because frank is realistic about his capabilities and what he can accomplish. Kill a few drug dealers there's less product on the street for a few weeks or months. Kill a murderer there's only frank left. Changing regimes takes time. Killing the top leaders leaves a nation in chaos as middleman and strong men assume power in the vacuum. He'd go from killing 5 or 6 really bad people to suddenly a dozen more pop up to replace them. He would need to groom a replacement. Empower them to take control. And ensure they have support of the right people and the population. Killing a gang is like stepping on an ant. Killing a dictator is like kicking over an anthill. Frank can't spend 15 years playing kingmaker behind the scenes for just one isolated dictatorship when he's better suited helping neighborhoods and people today.
