No... everything is relative... depend on Sea Power or not.... ultimate success depend on circumstances and factors not Sea Power... Sea Power will be very important, vital or not.. depends circumstances...Didn' t ultimate success in any colonial venture ultimately depend sea power?
France was defeated because they alwys were very weak in Seaborne... both in land as in Sea.. they were never as Portugal...and of course not as Spain or Great Britain. Would it be possible to France have defended Canada or India against Great Britain? Yes.. why not?
But France was a Continental Power... not so much interested in Colonial Powers (as later Germany, Russia or Austria-Hungary)... France was only interested after the defeat in 1870/71. So, in the days of the Colonial expansion.... France was a weak power in Sea and in Seaborne land...they didn´t lost the Empire because they have not controlled Sea Power but because they were weak in Canada and in India. Too much weak. They were strong in Europe but not in the World.
