Has Trump reshuffled the cards for Europe?

Abstract:

When Donald Trump, the next President of the United States, declared that 'NATO may be obsolete' during the campaign, he most likely had only a vague idea of how he would act upon them, but one can assume that if he made the statement, it is because he knew it to be a vote-winner. And win he did. This brief, published immediately after his election, wonders whether it had reshuffled the cards for European diplomacy and defence.
