Macron's oral English sounds terrible too. I laugh when our media says he is (somewhat) fluent.
That's a joke.
I even suspect he does it on purpose to some extent, overdoing the French r pronunciation because it is supposed stylish or sexy to English-speakers...

Many of them would be disappointed if we didn't do it, or so I heard. They think the overdone French accent is something pleasant or funny, at least to their ears (certainly not to mine).
Besides, Macron does some grammar mistakes out of carelessness that a 10th-grade kid should no longer do.
I have to read English-written documentation every day and my English is better than his.

Heck, we're not trying to be gentle seducers these days. We should be trying to be serious, reliable and relentless.
