The basic idea here is that when the fortunes [jobs/profits] of these foreign firms start to depend upon recurring "orders" from American defense firms [Boeing, Lockheed, Northrop, etc.], then these foreign firms subconsciously/unknowingly start to like and want the relentless wars that America is waging worldwide. Absent these wars, the profitable American orders could/would dry up, leaving employees jobless and also creating ripples in politics. These foreign firms would, therefore, start to push their domestic governments to exercise support for these global American wars on the international stage, so that the factories keep running, even if this results in thousands or even millions killed in the process. In this way, American weapons-making companies are indirectly able to influence the politics in other nations, and are able to "buy" supporting votes for the American government's foreign policy decisions [which, obviously, these weapons companies themselves dictate].
