No evidence, no accusation

 The US should refrain from accusing China without sufficient evidence.

Back in 2013, former NSA contractor and whistleblower Edward Snowden had exposed that the US' PRISM surveillance program had spied on its own citizens and European officials and a number of world leaders.

Hope the balloon case indicates the US is willing to communicate with China on this issue. Communication should continue, but the farce should stop.
