I'm looking for a proper antonym for the word 多難 in a context where it's meaning is 'many difficulties'. Would for example the adverb 難なく be appropriate? It translates to 'easily' according to my dictionary.
I've tried searching the web and I'm certainly not happy with the antonym 多幸 provided on this page: thesaurus.weblio.jp
Ultimately I'd want to use the anotonym to reverse the meaning of the news headline 「拡大欧州、多難なスタート」 which roughly translates to "Expanding Europe – Start with many difficulties".
