The US-Israel-Azerbaijan "alliance" isn't really an official alliance per se, but they have been building a pretty strong working relationship in recent years, especially in terms of defense, energy, and regional security. Azerbaijan and Israel have been growing their military ties, with Azerbaijan buying a lot of advanced weapons from Israel—especially drones and missile defense systems. The US is also involved here, with intelligence sharing and occasional joint military exercises. Since all three countries are concerned about Iran’s influence in the region, there’s a lot of alignment in that area.
Also, Azerbaijan is stuck in this weird spot geographically—it's right next to Iran and Armenia, so it has to balance relationships. But it has definitely moved closer to the West in recent years, partly because of its strategic importance. The US and Israel both see Azerbaijan as a key partner for regional stability and countering Iran.
first read about some secret alliance between the US, Israel and Azerbaijan against Iran 18 years ago.
Since then, there has been a lot of talk. Mostly empty.
The "secret alliance" of these three countries is mostly a "product" of the imagination of sensationalist journalists.
Aliyev has never been to Washington!
He has never been to Israel!
A strange alliance, isn't it?
Especially considering that the President of Azerbaijan will make a state visit to China today.
Although the US clearly looks like a decrepit hegemon, Trump should not despair, he still has a chance
Regardless of our relations with the US, Israel or any other countries, Turkey will always be our number one priority. This has been the case for all these 33 years of our independence, and it will be so. From the very beginning, we have had a coordinated foreign policy with Turkey on many issues. By the way, all countries except Canada

have known about this for a long time.
