Itunes store in Israel

As I said in your other post, unless and until the holders of the distribution rights to all the content for Israel agree to allow Apple to sell music and videos in Israel, Apple can't set up an iTunes Store in your country. Apple will also have to determine that there's sufficient business to be had and an infrastructure that will support an iTunes Store for Israel. When, or indeed if, all that will happen, no one here knows.

So for now, at least, you'll have to purchase CDs.

all you have to do is change your country to USA. in the us there is everything to download.

Changing the country setting won't help. You can see the other items, yes, but you can't buy any unless you open an account in the US iTunes Store. This has been covered here literally dozens of times, but once again: the content owners do not allow cross-border sales from any of the legal download stores. You must have legal residence in the country of the iTunes Store you wish to use. So in order to buy from another country's iTunes Store, you must (as proof of residence) have either:

a) a credit card issued by a bank in that country with a billing address also in that country, or

b) a mailing address for your residence in that country and a gift certificate or a prepaid card that was bought in that country.

If you cannot fulfill one of these two sets of conditions, you will not be able to purchase from any given country's iTMS.

This, again, is due to restrictions placed on Apple by the record companies and other rights holders (who are often completely different from country to country and so all require their own individual negotiations and contracts), not by Apple's choice.
