The bully's statement of political motives for charging Huawei executive Mang Wanzhou provide legal arguments for Canada to refuse to extradite her to the US.

I distrust Huawei products; I suspect them of spying for China. (US companies are known to spy for the US; under the PAT RIOT Act, they are compelled to.)

However, the case against Ms Mang has nothing to do with privacy or spying. It is about allegedly violating US sanctions on trade with Iran, sanctions which the bully applied in order to destroy the nonnuclear deal with Iran. It is arrogant for the US to try to make foreign countries follow US sanctions.
