(ANSA-AFP) - ATHENS, APR 2 - Greece will spend 25 billion euros through to 2036 in the "most drastic" defence overhaul in its modern history, Prime Minister Kyriakos Mitsotakis said on Wednesday. The drive, which includes a new anti-aircraft defensive dome, is designed to address rapidly changing geopolitical challenges and fraying transatlantic ties, Mitsotakis said. (ANSA-AFP).
