The US Defense Intelligence Agency (DIA), is but one of many organisation waking in fright at how behind the US is compared to Russia and communist China. Space has become a new battle ground, with China and Russia conduct attacks against U.S. satellites with lasers, radio frequency jammers, and cyber-attacks every day, as part of war games. Usually the damage can be reversed, or repaired, but that will change in a hot kinetic war, where the Russians and Chinese will mean deadly business. According to the Pentagon's 2021 report to Congress on China's military capabilities: "The PLA continues to acquire and develop a range of counterspace capabilities and related technologies, including kinetic-kill missiles, ground-based lasers, and orbiting space robots, as well as expanding space surveillance capabilities, which can monitor objects in space within their field of view and enable counterspace actions." This threat is right now, and rapidly expanding.
