ELI5: Why doesn't the US want Palestine to gain statehood?
gpt
Well, you see, the people who live in Israel are mostly Jewish.  When someone is Jewish, this can refer to a certain group of people, a follower of a certain religion practiced by those people or both.  The Jewish religion is the religion that was like the mommy for the Christian religion and, in fact, the early Christians were also part of the group of people who call themselves Jews.

The Jews used to live in Israel a long time ago, but around the first century AD, when Christians believe that Jesus Christ lived, the Romans moved into Israel.  The Romans told the Jews that they owned the country now and that they were going to be part of the big country, or Empire, that the Romans controlled.  As you can imagine, the Jews weren't very fond of this and fought the Romans to make them leave.  

Pretty soon the Romans got so angry that the Jews kept fighting them that they decided to send them all to separate timeouts in different places in the Roman Empire.  Some people call this the "Diaspora".

For almost 2,000 years, the Jews lived in different places throughout what we now call Europe, Russia and Northern Africa.  All of the people who lived in these places before the Jewish people moved in practiced a different religion than the Jews though and in some places, like Europe, people didn't like the Jews because of this.  This wasn't helped by the fact that Jews handled a lot of the money for the Kings and Queens in Europe especially and many became wealthy because of this.

About 80 years ago, things started to get pretty bad in the world because of a big fight that a lot of the countries in Europe had, called World War I.  A country called Germany lost this war and had to pay back a lot of money to the other European countries because of it.  Because of this, a lot of the people in Germany became poor and started to get angrier at the Jews because they thought they were hoarding money.

After a while, things started to get a little better and Germany became powerful again.  The anger against the Jews didn't stop though and eventually the leader, or Fuhrer, of Germany devised a plan to *kill* all of them and to try to take over Europe once again.  Because there were a lot of people who didn't really like the Jews throughout Europe, no one really stood up to stop the Fuhrer right away and him and his men killed lots and lots of Jews.  Eventually the Fuhrer was defeated though and the war was stopped.

After this though, the Jews were pretty sick and tired of not having their own country and not being able to rule themselves.  Because of this, many Jews began to buy pieces of land in an area that was informally known as Palestine, but was really their old homeland, Israel.  They couldn't just move everyone over there though, because the people around Israel were believers in Mohammed and Islam (which is also a child of Judaism, like Christianity) and didn't like the Jews either.  They needed to have help from another country to move back into their own country.

Meanwhile, there was a big country that you probably know of called the USA that *had* the power to help the Jews, but didn't have a whole lot of reason to use that power to help them.  Within that country there were a few people who had some power that believed in Christianity.  In these people's belief, their deity, Jesus Christ, was going to return to Earth to cause the Earth to end.  Now this may seem like a bad thing, and for many people it probably would be, but these people believed that when Jesus came back that they would be sent to a really nice place to live with him, even though everyone else would die horrible, horrible deaths and suffer forever.  Because of that, they wanted Jesus to come back soon.

One of the things that had to happen, these people believed, was for the Jews to live in Jerusalem, Israel's capitol, again.  So they started raising money and asking the government to help the Jewish people move back into Israel.  Eventually the government of the USA ***did*** help the Jewish people resettle Israel and for their help, got a really good friend in a place where they didn't have a whole lot of friends before.

There was a problem though.  In the time that the Jews didn't live in Israel and Jerusalem, other people moved in.  For the Jews to be able to move back, these people had to move out.  They had no place to go though!  So they've been living alongside the Jews since they came back in 1948 and haven't been all too happy about it.  

Occasionally they will lash out and try to kill the Jews, but because they are poor and have no real military or government, they don't do it very well.  The Israelis (as we call the people who moved back to Israel) have the power of the USA behind them, which gives them access to lots and lots of powerful weapons.  So for every person that a Palestinian kills, Israel will kill 10 or 50 or 100.  Obviously this is no way to live.

So there are people who want the Palestinians to have their *own* place to live so that they don't have to fight and die any more and maybe they won't be as poor either.  There are two groups of people who have a lot of power who don't want that to happen though: hardline Israelis and hardline Christians.  And the end of the story is that these two groups have A LOT of money and make it so that certain politicians don't support the separation of Israel into two states.  The first group doesn't want to because they don't want to have to give up their hard earned land, and the second group doesn't want to because then they might have to live on this Earth and the people who don't believe what they believe will get to live their lives too, which has always been a source of contention among them.
