We live in a time of populous, wealthy dictatorships that have computer-science expertise are openly hostile to the US and Canada.
North America is only about 5% of the world's population. [1] (We can assume that malicious actors are in North America, too, but this helps to adjust our perspective.)
The percentage of maliciousness on the Internet is much higher.
Huh? The empirical evidence we have - thanks to Snowden leaks - paints a different picture. NSA is the biggest malicious actor with nearly unlimited resources at hand. They even insert hardware backdoors and intercept shipment to do that.
Enough to be cautious, enough to think about how to catch bad actors, not so much as to close yourself off and become a paranoid hermit.
