US global sanction power in action. it was predictable. Not really a news.
Yes, hypothetically had US not interfered at all, then its most likely the base case that most of EU would have gone with Huawei, in the sense that at least very few counties would have by themselves come out and banned Huawei from involvement. Indeed, UK is the prime case where they had already announced that Huawei could play up to a 35% role in the rollout but then retroactively reneged based on continued US pressure.
First it was the arrest of Meng/CFO that cast a black eye on Huawei international reputation, then it was the putting of Huawei on the entity list. These things in and of itself would have killed most any other company. And certainty fair or not, were in many nations thoughts and calculations when decided which vendor to pick etc...
Then came COVID-19, even assuming it was a natural event and that no nation had a hand in any sort of biowar etc the fact of the matter is the US government maligned China, with top officials like Cotton, Pompeo, Trump accusing China of Wuhan biolabs leak, repeatedly calling it the China/Chinese Virus, asking the world to unite in confronting China in terms of forcing China to pay reparations and also to decouple from China... all this propaganda served to influence the hearts and minds of many citizens around the world, with the US injecting the false attribution that all this was because of the CCP and therefore we must stop Huawei because Huawei == CCP , etc etc
Then the final blows came from the Trump admin going against Pentagon advice/recommendations (or at least what we ostensibly know publicly) and forcing TSMC to sever relationships with Huawei. This changed the security profile of Huawei 5G in that now the likes of the UK whom had previously okayed Huawei had to re-assess the entire thing, because in the future these chips will be made in China with Chinese supply chain rather than American vassal ones, and it adds to the risk because if Huawei couldn't survive the chip bans then there goes UK's 5G investment... By TSMC cutting Huawei off, it effectively made it too risky just from a operational risk standpoint for many nations to continue with Huawei, even when not adding in the propaganda b.s. of security/backdoors/CCP etc etc...
Most recently the US sanctioned all Huawei employees, this had the goal of setting back Huawei's ability to recruit talent from abroad/within and also the demoralize existing Huawei employees and affect them emotionally and personally and in short to continue to harass and cause troubles for Huawei... this is not unlike the NordStream 2 workers that were sanctioned because the US didn't want Russia to complete with it for energy
Now I actually believe there is more to this Huawei 5G thing than meets the eye.... I think part of the reason the US put so much pressure on other nations to change course on the Huawei/China issue is because its already shoring up allies for the coming Cold War which is soon to go hot, I believe America's intent is not just to curb China's rise but actually in truth what the US really wants is to harvest China, to carve China up into many pieces, and as a consequence also a complete regime change of the CCP, with a hot war in the SCS this year or latest by 2021, and with the intent to do a nuclear first strike on all of China if all else fails to collapse China from within and isolate China externally.
