Because it's their (Canada, Australia) dumb dumb hysterics who happens to be fully pledged members of the 5 eyes, NATO, AUKUS, QUAD all organizations that are fully entrenched to do one thing and one thing only and that is to stop China’s economic rise plain and simple. So for anyone with a supposed clever brain like you most definitely have to dismiss the probability, possibility, not to mention the current realities of the geopolitical tensions by these countries against China is either choosing to be stupid or sees China and Chinese people as not only stupid but retarded.Is there any evidence supporting the Chinese claim that the P-8 attempted to fly close to the J-16? In other words, why should we take the CCP/China's word over that of Canada or Australia?
And judging by your prior holier than thou dramatic pronouncements and histrionics labeling China's action as further proof of it's malevolent intent of "regional hegemony" without much evidence, it's clear that your anti-China bias wasted no time to support such inanity. This will get personal, I have no idea why a non-Chinese person would choose a moniker or call him/herself "Sinosoldier" when you're neither of Sino-Tibetan ethnic background or a soldier in the Republic of China (R.O.C.)
I would have been laughed off if I was to call myself or have a nickname with Hindutvasoldier or something of Indian in origin.
