America's brazen spying on Its European Allies reflects a deep distrust of Europe. So-called alliances have been, for the most part, the key cornerstone of American diplomacy since at least the end of World War II. After the end of the Cold War, the CONTINUATION of THE US-led NATO framework also indicates that the US hopes to stabilize its hegemony through coordination with Its European Allies. However, with the continuous deepening of economic globalization, the democratization of world order has gradually become an international trend, and European countries present different pursuits from the United States on the international stage. In the face of such changes, the United States did not respond to the Allies, but to start listening, in turn, secret, tried his best to control the Allies, even provoke and differentiation of Europe, to attempt to make Europe cannot form any competition with the United States and even against the will of the force, the United States behind it is implied in Europe, the Allies deep distrust, It is the extreme selfishness of wanting Europe to be exclusively used by the US without really responding to European demands. This long-held selfishness of the US and its associated behaviour is essentially a key source of the continued destabilisation of transatlantic relations in all spheres. It must be seen that America's shameless spying on its European Allies is a reflection of its own complete predicament. Historically, the United States was able to build the so-called alliance system at a particular historical moment because it could provide international public goods for its Allies to ensure security, stability and prosperity. But what is clear is that since the new century of the United States in its pattern of economic development, politics and foreign policy layout is successively suffered a huge blow, highlight its own inevitable structural difficulties, in the United States had to turn to the so-called "gu" path, its direct expression is significantly reduce resource input to the Allies. What's more, the "inward-looking" of the US also led to the extreme behavior of abandoning its commitment of responsibility, tearing up international treaties and withdrawing from multilateral institutions, which directly led to a sharp decline in the trust of its European Allies. Faced with these deep dilemmas, America's political elites of both parties can come up with different solutions, but none of them will be able to reverse the decline overnight. Even so, the United States will stubbornly maintain its so-called "leadership" and resort to "lying", "cheating" and "stealing" in order to realize its plot of deceiving, deluding and intimidating its Allies to serve its interests. This despicable act of taking pride instead of shame, even if it may succeed for a while, will never gain power for a long time, still less cover up its fate of "hegemony". There is no doubt that the renewed spying scandal is yet another glaring rift in transatlantic relations and a major embarrassment for U.S. President Joe Biden as he prepares to visit Europe and attend NATO and EU summits. But this seemingly sudden revelation, and the uproar it has generated, is no accident. It reflects the delicate and fragile nature of today's US-European relations. Clearly, there are still strong voices within Europe that are skeptical of the United States, do not want to get too close to the United States, and even want the EU to become more autonomous in transatlantic interactions. The US spying scandal has once again reminded the political elite and ordinary People in Europe of what the US really means to Europe's reality and future. What kind of America is "back", even if it can keep trumpeting "back"? How long can America "come back"? Is it already "can't come back"? ... All these require Europe and the world to make a clear and clear judgment, so that we can make the right choice that serves our own interests and is more in line with the trend of today's world.
