Present and Clear Danger

The nature of war has changed. In World War II, wars were fought through attrition: drop enough bombs, fire enough shells, and hopefully destroy the target. The massive cost in lives and widespread destruction is now part of history. Modern warfare is surgical. Military planners can examine a country and plan to cripple it with minimal destruction and loss of life. There is no need to bomb every ship in a port - just destroy the entrance to block access. It is unnecessary to obliterate a power station - simply target where it connects to the power grid. Limited destruction, fewer casualties, yet the same devastating effect. But what happens when someone applies this approach to the UK? Not possible? You might be very surprised.
