Pardon my snark, but people might take your question more seriously if it were written in English.
International Law does exist, in the form of conventions and treaties to which nations freely sign on. For example, the Geneva Conventions, which govern - among many other things - how signatory nations must treat prisoners of war. If a signatory country does not abide by these guidelines, then it is in violation of "international law."
But often, the questions are murky, as is the case with Israel's dominion over the so-called, "Occupied Territories." They are land taken by Israel in a war that was launched against Israel in an act of blatant aggression. Some of that territory (the West Bank), if held by an enemy of Israel, would be an ideal launching ground for devastating attacks against Israel, and therefore Israel has refused to relinquish control back to Jordan, or to the "Palestinian State." This refusal is considered by some to be a violation of international law, as is the oppressive treatment of the indigenous people of that territory.
Obviously, it's not a simple matter.
