An EU-US working lunch summit in Prague, to talk over mainly energy security and climate change, has capped off the European Union leaders’ weekend in a friendly atmosphere.President Barack Obama, fresh from a major nuclear non-proliferation speech, conveyed his country’s changed stance towards international efforts to mitigate global warming. The President of the European Commission, José Manuel Barroso, at the summit’s closing press conference, looked ahead to key talks scheduled for this December: “(On) Climate change, we need a success in Copenhagen. We welcome the steps taken by the new American administration – an increasing convergence between the European and American position on that matter. Only together we can convince others to join our common efforts to fight climate change.” Czech Prime Minister Mirek Topolanek, who is not even sure to stay in office till the Czech EU presidency’s term finishes in June, referred to controversial US plans for an anti-missile radar base on Czech soil. Topolanek said: “Bilateral discussions took place and I think President Obama spoke out very clearly: the anti-missile project will not end.” Obama urbanely put behind him Topolanek’s recent cuts about his economic stimulus plans. In a nutshell, the key words of the day were: fewer nukes and more security, sustained trade, less pollution and different energy use.
