His 2003 book '' Empire Lite '' attracted considerable attention for suggesting that America , the world 's last remaining superpower , should create a " humanitarian empire " . This book continued his criticism of the limited-risk approach practiced by NATO in conflicts like the Kosovo War and the Rwandan genocide .
