Not in disagreement. My first thought was the more active naval stance we are taking around the globe. Strategically placing assets to block ports, blockade bad actors, protect the sea lanes for shipping.
Shipping is still the quickest way to move large amounts so men and materials.
Or if it’s word-play, he could say ‘watch the water, man’ and we could decode = Wasser man = DWS, for example, or her brother in NY. If we were gazing at a glass of water on our dashboard that suddenly began to ripple/wave, we could deduce a T-Rex a couple blocks behind us. Since he’s mentioned watching the water numerous times and obviously none of us are getting it, we’re gonna need to buy a vowel or two if, indeed, watching the water is important.
