Now You Know That Israel Has Nuclear Weapons

Now the world has known that Israel got a Nuclear weapons arsenal from long time that in 1970s Israel offered to sell nuke arms to South Africa according to declassified secret Southern African documents that go back to 1975.
Now the world has another evidence of what we have been saying from a long time , what is going to happen !!??
Nothing I am afraid , nothing will happen as the big countries know from a very long time about the Israeli Nukes arsenal , in fact they did help Israel a lot in its nuke program , this is from one side. From another side Israel does not have to defend or open its nuclear facilities for inspection because it has not and will not sign the Nuclear Non-Proliferation Treaty.
Israel does not have to obey anyone accordingly and thus aside of the noise nothing will harm it from this exposure regardless of their official denial.
Mohamed ElBaradei was often criticized for keeping his eyes shut on the Israeli Nuclear activities during the IAEA and he fired back saying that the IAEA could not do anything to Israel because the later did not sign the treaty unlike the Arab countries  Egypt which he wondered why they signed the treat in the first place.
Despite the fact that the Israeli Nuke arsenal will not be used against us in perfect world but in real world we have to wonder why we have signed the Non proliferation treaty so early especially how uninterested our regime is in reviving our nuclear program in the first place. I believe President Sadat did a mistake by signing this treaty.
