Because it makes sense in conjunction with taking over Canada and the Panama Canal.
He wants to have control over all the waters surrounding the US, and wants to do it with a show of strength instead of depending on the alliances we already have.
Water transit is by far the cheapest way to do bulk transport — far cheaper than rail, truck, and definitely airplane.
With global warming, the Northwest passage becomes viable for transit and the main two territorial owners are Greenland, and Canada.

因为这与接管加拿大和巴拿马运河是一致的。
他想要控制美国周围的所有水域，并且希望通过展示实力来实现这一点，而不是依赖我们已有的联盟。
水路运输是目前最便宜的大宗运输方式——远比铁路、卡车，当然还有飞机便宜。
随着全球变暖，西北航道变得可行，而主要的两个领土所有者是格陵兰和加拿大。


Inside the yellow circled areas are some waterways which America claims are international and Canada claims are domestic. Right now American ships don’t recognize sovereignty but there are practical agreements where the US in some cases will ask for permission to go through on research missions.
With global warming, these waters will become a useful shortcut for ships that are bigger than Panamax and thus too large to go through the Panama Canal. Better than going through the Straights of Magellan.
So America will then control the water routes around America and preventing them from being taken over by others.
My prediction: he’ll go after Cuba next. Far too close to US soil and hostile.

在黄色圆圈区域内有一些水道，美国声称它们是国际水域，而加拿大声称它们是国内水域。目前，美国船只不承认主权，但在某些情况下，美国会通过实际协议请求允许进行科研任务。
随着全球变暖，这些水域将成为比巴拿马型船更大的船只的有用捷径，这些船太大无法通过巴拿马运河。比通过麦哲伦海峡更好。
因此，美国将控制美洲周围的水路，防止它们被他人接管。
我的预测：他接下来会针对古巴。离美国领土太近且敌对。
