Another pernicious article to drill down in public opinion that "there is a risk and they cannot be trusted".<p>This is public opinion manipulation on a vast scale.
What most do not realize is that it is not about Huawei. The Huawei ban is nothing but an attempt of Trump to force China into a deal that it does not want. We can only speculate what will happen but I am pessimistic about the consequences for all of us.<p>The Huawei ban is making the whole world to realize that they depend too much on the US and all who realize this will work (jointly?) to reduce or eliminate this dependency which ultimately means that the US will sell less products.<p>Russia and China have been increasing their gold reserves to be able to get rid of the US dollar and there will be a new way of trading. Since economies of India and China are growing, the economy of the USA reduces (relatively). Europe, China, Russia, India, Iran, Irak and other countries do not agree with US policies, so the risk that US policies will fail some day should not be underestimated.
