It is a bit rich to hear a Brit complaining about anybody else's bid at "world hegemony".
'There had taken place, in the half-century or so before the [1914] war, a tremendous expansion of British power, accompanied by a pronounced lack of sympathy for any similar ambition on the part of other nations... If any nation had truly made a bid for world power, it was Great Britain. In fact, it had more than made a bid for it, it had achieved it. The Germans were merely talking about building a railway to Bagdhad. The Queen of England was Empress of India. If any nation had upset the world's balance of power, it was Great Britain.' t. J. Remak
It's not at all surprising to anyone familiar with the history of British foreign policy. It's the exact same line used to express annoyance by the Kaiser, or the Fuhrer, at British opposition to their territorial ambitions. STATUS QUO Mr. SPEAKER, HARK CRY STATUS QUO
Furthermore, the article you quote explicitly supports the notion that EuroCorps (or whatever they're calling it) is intended to fill the gap left by a very plausible US (and UK?) withdrawal from NATO, not so they can bring Merkelism to the world at the barrel of a gun.
...Where has the UK withdrawal entered your mind from? Plus this notion is easily dispelled just by the simple fact that these plans pre-date the US President's bid for candidacy in the RNC, let alone their actual election. Much like the EU trying to supplant the dollar since Bush or the EU Defence Agency enlargening even to areas of Europe NATO was reluctant to expand, it stretches the imagination to perceive decades of planning as a temporary response to a future President they could never have predicted. Where stated ambition and observed action coincide, it is illogical to ignore evidence in favour of rhetoric. In particular, US politics does not have an especially subtle rhetorical style shall we say, whereas in Europe everything is as polite as can be. Hence, mention of purchasing petroleum in euros or supplanting the American-led alliance with an autonomous European force, without alerting the Americans to the consequences of an autonomous European force conflicting with American foreign policy.
This isn't a new idea. And not surprisingly, it last gained traction and prominence during the Bush years, when the US started making all sorts of unilateral foreign policy moves. If the US can elect a rational government who doesn't want to tear up the norms of the international system (which would mean neither Trump nor Sanders), the push for a European unified military would fall apart.
If it is not a new idea, you should be familiar with its reality. If you are familiar with its reality, then why pretend as if this is some conspiracy you have only just discovered? I find it thoroughly dulling when people are somehow capable of rejecting the very words EU Presidents and Commissioners speak. European world hegemony is not a new idea; in some circles, it is tradition. Whatever the EU shall believe, whatever the European peoples should not believe, I shall not wish to be a part of this bid, any more than I would support a Napoleon, Wilhelm or Hitler. It's not terribly worth it, while the costs of winning or losing are rather grave
*EDIT
Do you need the EU President shouting "USA #2, USA #2, USA #2" whilst burning a bucket of McDonalds, Iphones and Eagles?
