'NATO should follow the Madonna-curve, and not wait till its controversies escalate into public wrangles. The argument that tinkering on the edges will do since all challenges can be dealt with one at a time simply does not hold. To be successful, NATO needs a package-deal of painful compromises, where each member state has to give and take. This requires a comprehensive reform effort which only a new strategic concept offers. The quality of adapting to new tasks whilst staying true to one's own principles is something which business analysts qualify as the Madonna-curve. This curve is named after the legendary pop-diva who reinvented herself each time her style and stardom went into inevitable decline, but whose audacity has lifted her up to ever higher levels of relevance and fame.'
