That might be a tad harsh - I'm sure that now progressive lawmakers have been made aware of the loophole by the news article that they are working on laws to fix it (previously they may have assumed that companies would just act in good faith in doing the right thing here, or failing that, that the US wouldn't send arms over to a country found to have plausibly committed genocide).

Alas, that process is quite slow, so I am currently putting my hopes on the lawsuit mentioned in your article. Hopefully the courts will decide to apply the brakes until a legislative fix can be made.

I hope I'm not being too optimistic here.
