Trump's defence concerns

I confess I had been somewhat puzzled by the agitated reception given in some quarters to the news that I had supplied the missing technical expertise that allowed the North Koreans finally to complete their inter-continental ballistic satellite launcher. A call this morning from Trump supplied the answer...
Trump alone among recent US presidents has never quite trusted me, and in fairness I can understand why. Early in his career as a property speculator I ...lured is not quite the word I want.... I involved him in a rather complex deal that financed the establishment of the main campus of my charitable research foundation, leveraging the value of the oil rights for a large section of the eastern Mexican Gulf over which I had an option. Through the deal I acquired the campus and he the option; how was I to know the option was worthless?
You might think Trump would at least credit me with the value of the experience, which has allowed him to become a somewhat shrewder player in the property market, but reasoning has never been his strong suit (odd the reinforced clothes some of these speculators wear), as this morning's call made clear. He started on his usual pugnacious note. Hey, what was I doing helping those commies. Why was I making missiles for them. Didn't I know North Career was unstable (I assume the spelling). And more of the same. I continued with the crossword until he lost steam, then patiently explained that the rocket which the North Koreans had launched with my help was intended to launch satellites, and I let him know, having exacted suitable promises of secrecy, that into the microprocessors that ran the guidance system for the rocket I had embedded firmware that, unbeknown to my clients, would never allow a ballistic trajectory outside their territorial waters.
I could tell that Trump didn't entirely trust my answer. OK wiseguy, he went on after a few moments of muttering to himself, if you're so smart answer this. Suppose they launch a satellite, and suppose it can get itself into a geo stationery (I assume the spelling) orbit. And suppose that orbit is right on top of Washington DC. How do we know there ain't a nuke inside it? Huh? And how do we know one day they flick a switch and a bomb-bay opens under that baby and out drops an H-bomb straight down on DC. I don't remember quite what he said next, as 17 down was really bugging me: 'Cervantes wearing cricket pad has a bit' (9).
