The modern corporations, the modern financiers, are funny things. They are in a constant drive to compete to out-exploit and out-accumulate each other, which steadily immiserates their respective societies, driving simultaneously the drive to war universally as economic activity saturates globally and then draws down the surplus upon reaching its expansionary limits. Besides the branches of the military industrial complex and its ancillary industries - which admittedly are gargantuan - much of the corporate and financial world would very much like the process of accumulation to go on indefinitely, albeit with minimal jostling and disruption and precarity.
The captains of industry and financiers whine and stomp their feet about being denied access to their increasingly hostile foreign markets, and go behind the state's back to subvert sanctions and other hostile forms of economic activity, and so on, while their brethren in military contracting lick their chops, encouraging an ever more assertive and aggressive national security state as conditions deteriorate.
There is of course an adventurism at play here: oligarchies are always behind the warships, licking their chops at the prospects of financing the wars and then getting their hands on the spoils of war, which in the modern era translates to privatization and economic dispossession. But historically, it can get hot enough to where a given set of oligarchs can lose everything, who were doubtless thinking it couldn't possibly happen to them beforehand.
