Longest Undefended Border? No more.

It used to be a matter of pride for the US and Canada, bragging rights on having the longest undefended border in the world.

Now that's history. US Army Blackhawk helicopters are doing armed patrols of the border between Montana and Alberta. Unmanned drones are scheduled to be added to the choppers. All of this to protect our northern border. Why not just build another fence, like we are doing on the southern border?

BTW, you'll note from the Google news search that nearly all of the sources for this information are Canadian. You don't see a whole lot in the American media about this kind of stuff.

Besides, I've always maintained that the fence isn't there to keep THEM out; it's to keep US in.
