This person leans conservative but doesn't like what Trump did w/ Israel
What Trump did with and for Israel on a strictly political basis was right and in fact excellent. He let the whole anti-Israel world (all countries other than America at that time) know that the USA was 100% behind Israel, and Jerusalem is indeed the capital of Israel.
he thinks wealthy Jews control the whole world or something to that effect
This is an entirely separate issue, and it is perfectly true that wealthy Jews -- mostly billionaires -- control world affairs, the media, the social media networks, and politics worldwide.
And they do in fact manipulate world events.
just wondering what others know about Israel and the Palestinians... Some say the latter are not even a nationality...
This again is a separate issue. The land of Palestine was under the Romans and it was in 70 AD that the temple, Jerusalem and Judea were destroyed by the Romans and the majority of Jews were driven out after hundreds of thousands were slaughtered. After the Roman empire fell, the Arabs and Muslims (Turks) began to control Palestine, and even the Crusaders were unable to remove them. Then Palestine became a part of the Ottoman (Turkish) empire from the 15th to the 20th century. It came to an end in the early 20th century and Britain was given Palestine as a protectorate.
In the meantime, the Jews who had dispersed from Israel went to various European countries, and they even managed to make a large number of converts in the Khazarian nation (Central Asia). These are the Ashkenazic Jews. Because of anti-Semitism and the persecution of the Jews throughout Europe, the Zionist Movement began in Europe, and eventually Great Britain gave a portion of Palestine to the Zionist Jews. Thus the nation-state of Israel with established in 1948.
The Arabs living in Palestine thought they had total rights to this area, therefore there were many conflicts with the Arabs, who eventually began to call themselves Palestinians. But the leaders of the Palestinians never wanted to co-exist peacefully with the Jews, and rejected each and every peace plan. The fact of the matter is that Jews have a right to Palestine under the Abrahamic Covenant, and even though Israel is a secular nation, God has allowed them to be established and even flourish in Israel. This is a part of the fulfillment of Bible prophecies.
Arabs and Muslims in the meantime vowed to drive Israel into the sea, and ganged up on Israel many times. But the Six Day War proved that Israel was superior to all their armies, and could have easily taken full control of Palestine. Since they failed to do that they have had nothing but trouble from the Islamist terrorist groups Hamas and Hezbollah, because Iran has not only been funding those scoundrels, but providing them with military equipment and munitions (including rockets for decimating Israel).
The recent conflict in Gaza was basically funded by Iran, since Israel has been undermining all of Iran's efforts to get nuclear weapons.
But Joe Biden is primarily responsible and should be held accountable for this unnecessary conflict. At the same time Israel should not have declared a cease fire until they had cleaned out Hamas. So now Hamas and Iran are claiming the victory, and Israel is back to defending itself. In the meantime, Biden wants to give Iran every advantage to the detriment of Israel.
The Palestinians are not a nation as such but a conglomeration of Arabs who have been living in that area. The ordinary people are victims of their evil leaders, and the evil leaders are controlled by the demons in Iran (the mullahs and ayatollahs). Given all the billions of dollars which have poured into Palestine, each and every citizen could have been living better than any American. But instead, all that money was poured into trying to destroy Israel. Ultimately Satan is behind this hatred for Israel, since the Arabs who live within Israel have the same rights as their Jewish neighbors.
