Has america's position declined markedly? The era of hegemony may no longer exist, Turkey is not afraid of the United States to threaten to buy a batch of S-400 anti-aircraft missiles from Russia.

Because Russia's missile system is too powerful, so as Russia's latest anti-aircraft missile, S-400 has always been uneasy for the US military, the commander of the US Armed Forces Strategic Command John Hayten also admitted two days ago that the current weapons of the United States are not enough to counter Russia's missile system, so the United States has always regarded Russia as its own nemesis, and constantly sanctions Russia, just to interfere with Russia's development, in the military field to the United States less threat. But Turkey buys anti-aircraft missiles from Russia, so why should the Americans threaten Turkey and prevent them from buying them?
In fact, the answer is also obvious, because the United States is afraid of Russian missiles, and Turkey also wants to buy its most advanced anti-aircraft missiles from Russia, which threatens the United States, which makes the US government even more uneasy, so they began to threaten Turkey, thinking that as long as Turkey buys S-400 air defense missiles from Russia, it is against the United States. In late April, U.S. Secretary of State Blinken "warned" Turkey that Turkey and other allies of the United States should not buy weapons from Russia for any reason, otherwise they would be subject to major U.S. sanctions and would affect relations with the United States.
It is worth noting that the United States is actually threatening Turkey more than this time, because Turkey has purchased S-400 air defense missiles from Russia in 2017, therefore, the United States has launched sanctions against Turkey as early as 2019, and the US Congress has threatened Turkey to abandon the plan to buy S-400 air defense missiles from Russia, but Turkey is not afraid of US threats and sanctions, Turkish Vice President Oktay has said that Turkey will not yield to US sanctions. And it will not abandon the plan to buy the S-400 from Russia, however, from the current situation, Octay's previous statement is indeed not blown.
According to the Global Times quoted Russian media related news reports, recently, Turkish President Erdogan said that Turkey will buy a batch of S-400 air defense missile systems from Moscow again, and the Russian arms export enterprises also said that they agreed to give Turkey the supply of S-400 demand, and the contract between the two sides will be signed before the end of this year. Erdogan also said that we will not hesitate to purchase these S-400 air defense missile systems from Russia, and in the future development, Turkey and Russia will take more measures in more areas.
Some analysts say that the so-called strong dragon can not suppress the snake, so it seems that the hegemony of the United States has indeed been broken, but the United States should indeed wake up, the era when the United States can call the wind and rain has passed, they should face up to their international relations with all countries in the world, and now many countries have stabilized their national defense strength, and are not willing to bow to the hegemony of the United States, if the United States is not willing to wake up from the dream, in the end it will only harm itself.
