That is not to say bombing doesn't have its uses in war. The bombing of the oilfields of Ploesti in Romania severely damaged the German war machine. But it took Russian boots on the ground in Berlin to effect a German surrender.

Being Serbian, the bombing campaign of 1999. was successful. It lead to the (temporary, 12-years long) regime change, and to the de-facto independence of Kosovo. It ended the war.
