Lets make this a true dilemma:


the problem is, you may only press one button(but you may press it as many times as you want)

i spend a good 5 minutes and i cant think of a reason not to kill em all. they are all guilty anyway, they didnt keep their terrorist in check, its not really the outsiders job to clean up their mess.
However it is smarter to kill off all Jews first, since they created this tolerance propaganda in the last few decades. And this tolerance had made it possible for muslims to take over and DEMAND their way of life over the way of life of whatever country they went to. And the irony is, they migrated, because their way of life is shit and causes trouble. They are filthy idiots that infect other cultures and deserve to die.
You should however look at Putin as an example of a SMART man, who knows what i just wrote. He didnt kill them off, he won the elections and made sure the Russian government is not corrupted, then he enhanced Russian culture and values and told the rest to fuck off, or integrate. You cant go to another country and demand they change their ways to fit you. That is straight fucking stupid.
So you'd kill every single jew and arab? Tell me how many jews and arabs have you personally met and got to know? Rass here is a jew, can you not think of a reason not to kill her?
Maybe I'm wrong about you, but people I have heard say similar things are all pretty much isolated hermits who get their info mostly through biased media sources. Why do you think the commies were/are about keeping the population isolated and inside the borders Meta? Or about things like internet restrictions? Because interaction with other cultures opens the mind in remarkable ways.
Take someone who has met, partied, fallen in love with arabic or jewish people, got to know them as human beings and understood their problems from their own perspective, and talk about your views with them. That person will shake their head and find extremist views like yours immature and uninformed. Things aren't simple and as black and white as you think. You only think that because it's easy to rationalize and see humans as abstract numbers with no reason to be kept alive, if you've never interacted and met those people to find out the multitude of reasons they deserve to live as much as your next door neighbor or best pal.
