Where will Yemen's refugees go to?

It's important to see this coming because the dynamics there are that Saudi Arabia cannot survive forever with Houthi rebels armed by Iran there. So, the likely outcome is most of the Infrastructure (for anything) in Yemen will be destroyed in the coming years so Houthi rebels can't use this infrastructure against Saudi Arabia.

But, what about all the Shiites and Sunnis caught in the middle of all this who often are not on either side really?

What will happen to them?

LIkely over the years it will be the same as Syria.

If they stay there they will starve, die of thirst, be killed by the war or leave.

So, where are the refugees that will leave Yemen over the next few years going to go?
