When Israel attacks Palestine, which is more important, American life or Israeli life, is it fair?

This is not comparable. It's not life that matters, it's national interest. If you are a poor man who has been persecuted for more than 50 years, you will get rich overnight, live in a mansion and get close to gangs. There was a big backer who became very good at fighting again, but the people living around you bullied you and you got revenge several times. The problem now is that there is an unsightly straw house in the yard of your mansion illegally occupied. There are a group of poor people with the same blood as those who bullied you in the past. They often play tricks on you and quarrel to divide your land. What would you do? The bigger problem is that you are afraid of affecting your own interests, and your underworld eldest brother won't allow you to tear down that broken hut. Isn't that bullying those people and giving them a good lesson when they challenge you?

Of course, these are all metaphors.

Now to answer your question, in the eyes of Israelis, the life of a natural Jew is the most precious, but for the hard-won living environment, there must be sacrifices, even for the United States, because the United States and Britain are his biggest backers, and only by relying on them can he gain a foothold in the Arab world in the Gulf. All men are created equal, which is the right given by God. This is advocated by capitalist society, but in fact, only the life of the ruling class is the most precious to itself. The United States will not mind sacrificing some American lives for a valuable Palestinian.

In the eyes of the ruling class, human life is just a set of numbers in the document.
