"unnecessary duplication of safety trials because the FDA doesn't recognise any foreign medical safety standards, not even e.g. the EU)"

I would say in some cases that is a good thing. https://en.wikipedia.org/wiki/Thalidomide

It's very hard to argue against a safety trial - of course if you duplicate safety trials then there will be occasional cases where you catch something that the original trial missed. But ultimately far more people have died or suffered because a medicine wasn't available yet than been killed or hurt by medicine being approved too early.
