Finish school yet?
Going to college?
Finish school first, then......
If your a citizen of the States, you ought to join here. If you have dual citizenship, then I would say go to whichever you plan on being for the rest of your life. If your an American, go there (Israel) to join their service, then come back here? Many Americans won't hire you because of their allegiance to this country. Of course, you will find some that will but many prefer American veterans. If you truly want EP, ( I assume this will change much as you get older, especially if you find out what it's really about), stay in school and work for the State Dept, high speed EP there IMHO. EP in the civilian world is extremely difficult to make a living at, too many folks doing it. Somehow, you have to make a name for yourself to get in the field. Military is not a bad start, but it's not the only thing they prefer. If you think because you might become a 3,872nd degree black belt, you will get in, not a chance. These are all good additional things but neither will get you into the field. You have to go somewhere like the State Dept that will get you a good reputation in it. State Dept is so important because those folks tend to know many of the people doing real EP, as many of them start their own companies doing such after retirement.
My suggestion, stay in school, college too, graduate and see how you feel then, after your graduate.
