U.N are useless.
In a century Israel will always be there,
Israel's entire existence depends on these guys being the top dogs.
In particular the US, as the head of Western civilization. So because you mention Israel will still there in a century, I'll give you some perspective.
A century = 100 years.
141 years is the time from where the British empire becomes victorious in Trafalgar (1815), becomes the world's sole superpower (1815-1940) and then suddenly realize they're no longer a superpower during the Suez crisis (1955). That's a very significant drop in power and prestige. A country that once control an empire in which the sun never sets, failed to perform against newly established Egypt.
Another perspective for you, an Edwardian era (1900-1914) boy who grew up watching something as complex as the Titanic getting launched from the slipway could only retired in bitterness when he reaches his elderly knowing that Russia, and not UK is the one's launching satellites and men into space.
By the 1960s, it's becoming clear that Europe is no longer in the game of top dogs. They're still a great power, but no longer globe spanning empires like they used to. Only the industrious America saves the West from its declining power vis a vis the Soviets. In fact it could be said, that America does all the heavy lifting to make sure the West stays supreme.
I don't what will happen in 100 years (2124), but whatever it is, it's very likely that the West's standing will not be what they are today. Because the top dog of this society (the US) and the Western society as a whole is on a decline. Every symptoms of a dying empire of the past (Romans, Persians, Arabs, Ottomans, Mamelukes etc etc) is clear for the eyes to judge.
You guys happens to tick ALL the characteristics of the age of Decadence :
So because you are already in the age of decadence. Israel, who depended on being parasite on Western society to advance its interest in the Middle East must've hoped that this age of decadence doesn't translate into collapse, because it eventually will.
Israel could cheer all they want but as long as they are not able to subdue the Islamic world to actually SINCERELY accepts their presence, they are living on borrowed time. And there will be no such thing as Islam accepting them, when our religion clearly defines them as the enemy of the faith.
The Taliban was once quoted as saying " You have the watch, but we have the time".
