The Pentagon said that China must be prevented from learning from Ukraine and launching drone attacks on their strategic bombers. The Defense News website reported on June 4th that General Alvin, the Chief of Staff of the U.S. Air Force, said that the drone attacks by Ukraine on Russian airbases had sounded an "alarm for global military defense and offensive posture." The U.S. military said that the U.S. Department of Defense was "shocked" by the drone attacks from Ukraine. Think tank media also warned that the U.S. Air Force urgently needs to strengthen its airport air defense systems to deal with potential drone attacks in the future. Remember last year when more than a dozen U.S. congressmen wrote letters urging the Pentagon to strengthen the defense forces at the U.S. bases in the Indo-Pacific region because if China could destroy 90% of the U.S. aircraft on the ground. At that time, the United States was concerned about China's missiles, but now that Ukraine has attacked Russian airbases, the U.S. is worried about China's missiles again. In response to this, we would like to emphasize that those who do not do wrong things during the day are not afraid of ghosts knocking on their doors at midnight. If the U.S. does not suppress or contain China and does not build an encirclement against China in the Asia-Pacific region, there is no need to worry about China striking first!
