The use of his first name was irksome. Still, he was doing a fairly decent job of not showing how much it ruffled his feathers. They were both leaders of countries, after all (though of course the president did not lead with as much authority as he did and was at congress' mercy more often than not). For now, he would play the gracious host, and not insist Lex use his proper title or face an ax.
"There is no profit in giving countries technology of this kind." Tariffs for Latveria were ridiculous thanks to the UN, and he was not keen on arming people with dangerous bots, especially if he intended to overtake the world someday.
Concerning the comment on magic, he only folded his arms. "There are reasons for its current instability." He thought about the magic-sucking room so many floors beneath the castle. He had blockaded it mostly, but it still influenced and pulled, breaking down the barriers bit by bit and needing reenforced often. "It is but a glitch." Because he didn't consider magic beyond fathoming. There was a science to it, and definite rules in place to manipulate such energy. But for people like Lex and Reed, the understanding evaded them.
Well, few could be genius in both areas as he was.
He lifted his gauntlet to gesture at Lex to go ahead. There were two prototypes before him. "I took the liberty of investigating some of your factories. You'll find that these can be cheaply massed produced with the materials used without compensating their quality. Especially easy to reproduce will be the testing trays, which will need replaced after each test. You can try it on yourself, if you like."
