Indeed.
Recently in Palo Alto for a few months. Saw lots of people protesting Tesla dealerships, lots of interesting and creative anti-Trump and Elon signs.
Not one word of Canada, of Greenland. Trumps stated goal of destroying Canada's economy to force annexation, or to outright just take Greenland seem not protest worthy.
Most people I spoke to seemed barely conscious of the issue.
To be fair, other matters may be higher pri in their minds, so if other events were not happening in parallel, it may be different.
But when 65 billion dollar defence hardware purchases are being dropped (they are), when future military purchases are not going to happen, when police cars, municipal vehicles are not going to be from US companies any more, when natural resources are going to be sold to the EU and China instead (sadly), the US is going to feel this for a very long time.
Because these are choices for decades. And it's not only Canada making them.
