Israel falls if the U.S. stops supporting them. We won't be entirely rid of kikes, but that's at least a good 2/3 of the kikes in the world.
All we have to do is take back the U.S., democratically. This won't happen overnight, but we can eliminate the problem in about 1 or 2 generations, easily. Here's a rough plan. We only need about 100-300 or so people to follow this kind of thing successfully, but it's definitely something we can do.
1) Determine which party of yours is dominant in your locale and run as a member of that party. It doesn't matter what your actual politics are - you can backstab everyone later.
2) Run for office. You don't have to go all the way to congress - having a sympathetic Mayor is good for the cause as well. You don't need a spotless civic record. (If you have a serious criminal record, just back off. But you can still get away with something relatively minor, like a DUI or something.)
3) Try to get a feeling for who your actual allies are. They won't be split among party lines - why would they be? They're just like you, doing what they can to snatch up some power for the cause! You can probably figure it out by voting records - voting along party lines on issues that don't really matter to the cause, while voting for the cause on issues that *do* matter is a great signal that you are one of us.
Don't wear any sort of visible sign or start saying "praise kek" or something. You're not an autist, you're a legitimate politician!
4) Have kids, and have at least one of your kids take over for you. You didn't think you'd secure a future for your people and your children in one generation, did you? If you can't have kids for whatever reason, then promote someone capable from your campaign and have them be your successor in spirit. Make sure they actually understand what's going on.
5) Once you've built a political network within this system to the point where about 33% of the people in the system are /ourguy/s, you can start acting seriously. If you've kept yourself relatively popular, you can help!
6) Remember, the job isn't done once Israel's cut off. You need to stay in power to keep it from happening again. You could also probably fix some other problems while you're there (and doing so will make you more popular, so that's a good idea anyway.)
So, if you go this way, you have 100-300 Holla Forumsacks killing off 12 million Jews. That's way more effective than if 100-300 Holla Forumsacks went and took their guns and killed 100 Jews each (which is a lot more Jews than you'd expect a single person to successfully kill!)
