The west is currently attracted to developing more smart bombs and drones. The west wishes to influence overseas countries that might harbour terrorists, and wishes to root out or kill terrorists that could be a threat to the west.
The drone has a long history. Germany towards the end of the Second World War unleashed V1 and V2 flying bombs on southern England. Counter measures included seeking to destroy their launch sites, and trying to shoot them down in mid air. The Germans improved their technology to speed them up and to move to mobile or better hidden launchers.
More recently digital technology has allowed precision use of these fearsome weapons. Western systems allow operators to programme the flying bomb, guided by satellite navigation, to a specific street address many miles away. The method avoids risk to allied western forces, as the bomb can be delivered with no western manpower needed anywhere near the target, either in a plane or on the ground. It can be fairly specific with the target, though its sucess depends on good intelligence, and on the just the right people being at the location bombed at the moment of impact.
The technique has its military disadvantages. There is no-one near the target to see the latest conditions on the ground and to authorise the firing from a suitable position. The enemy can claim the bomb did more damage that it actually did. No-one can be sure who, if anyone, was killed by a flying bomb strike on a building. If you are trying to win over hearts and minds, it is not a friendly way to assist. If you need to influence and assist a country into peace loving and democratic ways, you may need troops on the ground to train and assist local people in establishing law and order. If you are successful at killing terrorists, you may also be successful at helping them recruit more people to their cause. Successful remote bombardment can help the terrorists win over a local population against the outsider.
I have no objections to the west developing smarter bombs and drones. They may be needed. I do think the west needs to reflect carefully on where and how often they should be used. They may be politically counter productive. They can be morally wrong. The west has to recognise there are limits to how far we should go in enforcing our counter terrorist policy by authorised murder rather than through inter governmental and legal process. Our best protection against terrorist attack at home is good intelligence allied to proper control of our borders. Anyone authorising or triggering a smart bomb would be wise to ask for legal cover in our jurisdiction against possible future legal charges, and will need to remember that the country receiving the bomb may take a different view of its legalities. It is, of course, simpler where a state of war exists. There the issue of authorising the death of people is governed by the rules of engagement. In some case now smart bombs are sent into countries where no war has been declared.
