This seems to me to be a good case of Strat Comms. We tell the enemy that the gun boat is on the way to undermine their will and cohesion. They are showing cracks at the moment.
Notwithstanding this, without the support of NATO nations I believe we are on the way to Strat Failure. Forces that have been agreed to be contributed are not. The CJSOR is not being met. The nations involved in the fighting are very good at turning young muslim men into mincemeat, but without the political will the war will be lost. The flow of muslim extremists coming from Pakistan is greater than our ability to mince them. We have to win the ideological war (strategic) as well as mincemeating the enemy (tactical/Operational).
By the way - one of the nations with the most caveats relating to the employment of its troops are the Brits - don't go there.
