I assume because this question is in the World War I Category that you are referring to the Arab involvement in World War I.
Arabs were not attacked in World War I, they rose up against the occupying Ottoman Empire. They attacked the Ottomans, who of course, retaliated. The British and French promised the Arabs that if they joined with the Allies against the Ottomans, that they would be compensated with an Arab State over all of the Middle East. Suffice it to say that they Arabs were not compensated in that way.
Sindh.
Yes. The United States supported Israel midway through the war. The Soviets had already provided assistance to the Arabs.
They attacked and invaded Israel. Concurrently, they made the situation so harsh for Jews domestically, that 850,000 Jews fled the Arab countries as well.
Muslim Arabs
because israel came and made the Jewish part of palestine into the new state of israel and Arabs attacked, they lost the war and signed an agreement and the Arabs part of palestine was now part of Jordan. about 7000,000 Arabs fled israel and became refegees and lived in crowded refugee camps outside israel. many still live there and they believe there homes are stolen.
The question as worded is nonsensical. There is only "one Iraq country", Iraq and it attacked Arabs in 1990. If you are asking "Which Arab country did Iraq attack in 1990?" the answer is Kuwait.
No, they don't hate Arabs. It is the opposite,. They have strong relations with Arabs.

Not all Arabs are Muslims. So, Muslim Arabs pray in Mosques, Churches for Christian Arabs and Synagogue for Jewish Arabs.
