You have events completly backward, Russia was already invading when Macron said it. If you can't even get years in the right order you're not really arguing in good faith.
The point is that Russia didn't just turn around and go home when Macron threatened to send French troops to Ukraine. Because everyone knew they weren't actually going to do it. And they didn't.
Did you notice they also haven't invaded other countries so far? And that France now supports Ukraine's long range strikes?
