Second best French would be in the UK, I’d say. Second best Indian food would depend on which regional cuisine but I’d say the UK or Malaysia would come before the US. Second best Turkish is probably Germany. Second best Thai and Greek is probably Australia. The US probably does have second best Italian though.
I think there's room for reasonable people to disagree about specific national cuisines. Where I don't think there's much room for disagreement is that if you looked at the rankings for all the world's national/major regional cuisines, the USA would have the lowest total by a healthy margin.
