My humble view about Obama speech in Cairo

The world again was mesmerized by the speech of the men who are really can be called as a good speaker, so called as unique and unexpected speech, by the US President Barack Obama.. As well as we notified, the speech was about the US-Muslim ties, which held at Cairo yesterday..
He started his speech by saying he was honored to be in the timeless city of Cairo and few more praise before he gave 'salam' which he got the applause from the audiences..
From the beginning of his speech, i take it as it was a really good speech, really meaningful, so unexpected..
He also mentioned few words taken from the Holy Quran, as he saying "As the Holy Quran tells us, Be conscious of God and speak always the truth." (which was also bring him the applause again)..

What i wanna highlight here are a certain things that i think he still didn't get it..
First about the nuclear weapon, despite by saying "It's about preventing a nuclear arms race in the Middle East that could lead this region and the world down a hugely dangerous path. Now, I understand those who protest that some countries have weapons that others do not. No single nations should pick and choose which nation holds nuclear weapons. And that's why I strongly reaffirmed America's commitment to seek a world in which no nations hold nuclear weapons", but as we all known, US still are the largest nuclear weapon maker in the world, and how could you call this as FAIR??
It was really disappointing that Obama spoke about violence without admitting to America's role in violence on a global scale..
Why Obama never mentioned about the war fought in Iraq, Afghanistan, Latin America, Vietnam, etc..
We all can see clearly how America are so arrogant in effort to conquer the world which the fact that US had almost a thousand military bases around the world...
And about the peace of Christian, Islam and Jews..???
Maybe it is possible for Muslim and American to get together, but for Muslim and Jews..???? it still confusing, especially in the Israeli-Palestinian conflict ..
Obama should notified Israel first about the condition of unfairness which clearly can be seen at Palestine....
How is that possible for Muslim to get together with Jews while at the same time our brothers and sisters (Palestinian) being tortured everyday by the Jews over there???
What Obama should do is exert more pressure on Israel rule/ruler..
They should aware that Hamas just doing what they should in order to get back their right on the land of Palestine which is clearly belong to them...
And that's why, Hamas, slightly, won the most support in the last Palestinian election..
Why west power still wanna ignored this??

However, for sure, it is always good to have an American president speaking the hard truths. Today's speech was a good start. But this region is full of starts. It's the finish that feels like a mirage in the Middle East. History depends on follow-through.
