Translation struggles - Kuroshio Current being mentioned in a patriotic song


I'm trying to make sense of an old Japanese patriotic song [五・一五事件 昭和維新行進曲
陸軍の歌](http://dl.ndl.go.jp/info:ndljp/pid/1137450/7), and there's a line that
contains a reference to the Kuroshio Current. The event this song was written
about (the so-called [May 15th
Incident](https://en.wikipedia.org/wiki/May_15_Incident)) has zero connections
to the Kuroshio Current, and I think there must be some cultural reference
that I'm not aware of. It's in the last 2 lines of the second verse:

> 醒ませ{さませ}悪夢{あくむ}を 開け{ひらけ}眼{め}を (Wake up from a nightmare, open your eyes)  
>  **寄せる{よせる}黒潮{くろしお} 何{なん}と見る{みる}** (I have no idea what to make of this)

Is it indeed a cultural reference, or does the last line speak about the
Kuroshio Current as a physical object (and if so, how it is relevant to the
May 15th Incident)?




Probably due to Kuroshio's [strong
current](https://ja.wikipedia.org/wiki/%E9%BB%92%E6%BD%AE), they improve
[transportation of heat and things](https://confit.atlas.jp/guide/event-
img/jpgu2018/AOS15-09/public/pdf?type=in&lang=ja). The lyricist wanted to
encourage troops mentioning 黒潮. My interpretation is the following :

> 寄せる黒潮 何と見る The Kuroshio is forthcoming, how do you feel about that?(Why
> don't you get stoked!?)

It sounds like a typical phrase of rock concert like Metallica.

Possibly 陸軍{りくぐん} : Ground Force also did [long-distance-
swimming](https://ja.wikipedia.org/wiki/%E9%81%A0%E6%B3%B3) for their training
a lot. So, I guess the cultural reference and its physics are related.
