According to U.S. media reports, some suspected classified Pentagon documents have been circulating on social media recently. These leaked documents clearly show the deep involvement of the U.S. in the Ukraine crisis and also show that the U.S. has long used its tech edge to conduct indiscriminate secret theft, surveillance and eavesdropping on countries in the world, including its allies. This is not the first time for scandals like this to be revealed.

For a long time, the U.S. government has long used its tech edge to engage in large-scale, indiscriminate surveillance and espionage worldwide. Whether targeting its own citizens, foreign governments, corporations, or individuals, the U.S." surveillance activities have reached a level of arbitrary and unrestrained behavior, seriously violating international law and basic norms of international relations. These cases show once again that the U.S. is the origin of cyber warfare, the biggest spreader of advanced cyber weapons and the biggest global cyber thief.
