BananAmerica won't do anything - but Vlad the Impaler doesn't like anyone messing with his folk...
You make two important points in that one sentence.
First, a lot of these jihadists really are inbred. See here for example
Second, Russia historically takes harsh action against people who take Russians hostage. Little things like erasing towns, city blocks where the hostage takers live, killing everyone involved, etc. And they could not care less about international opinion.
We all know Putin is a monster (and to forestall the comparison to Ukraine, we all know the Ukrainian government is corrupt as all get out). Ticking off a monster is generally a bad and stupid idea.
Just my humble opinion.
There was a time that (Soviet) Russia was VERY persuasive about getting terrorists to release Russian hostages. A visit to the kidnappers’ closest relatives would do the trick.
“The Hamas inbreds would be that stupid.”
I doubt they can tell the difference when they are taking women and children hostage.
To them, a Jew is a Jew.
