Second - your ~'other countries would do the same' - is juvenile excusism, based on no evidence at all. Merely the unfounded rhetorical statement that ~'the other guys are equally bad/worse'.
You really think the PLA who was more than happy to initiate Tienamen wouldn't hesitate?
In 'other countries' I include primarily liberal democracies with nuclear capabilities - as USA is. Your ~'other countries would do the same' has no foundament in facts when it comes to them.
Your rhetoric is doubtful even when it comes to China or Russia.
Only when one looks at the likes of North Korea or Iran can one claim what you did with any validity. Your statement can only pass when measured against such low standards.
