Israel has a particularly close relationship with the United States via a decades long lobbying effort. Israeli media often debates whether or not the nickname "the 51st state" is accurate or not, and whether they are too dependent on the US. Israel has a program to fly Americans to Israel for free for two weeks as part of a cultural exchange program to build ties. They're heavily invested in this.
The UK and Australia are close allies too, but Israel is quite small (geographically the size of New Jersey) and only about 8 million - the total population of California's bay area, and surrounded by countries that often times are at best neutral. Israel has a strong incentive to win and maintain US friendship.
