No for several reasons:
Bitcoin can’t be printed at free will, we would return to the days of wars only happening as long as they can be afforded. Back in the gold era, stalemated wars had to come to peace because one or both sides ran out of gold.
An ETF as an investment vehicle isn’t going to be used to fund wars, it’ll probably just be used by corps and peoples 401ks. One can make the case that they’ll create paper Bitcoin here but anyone who’s paid attention to FTX, Celcius, etc knows what happens when paper Bitcoin is not backed with real Bitcoin.. Bitcoin has a funny way of calling people’s bluffs
