美方在美国本土放飞大量高空气球,持续进行全球环行,至少10多次非法飞越中国领空 - 1) Why PLA didn't shoot down? so Chinese missiles are paper-toy? 2) Why not show any evidence? 3) Global travel must pass so many countries from American (east ward) to China, why these countries complaint this? Common sense - show evidence when you sue others!
