How about what you would suggest?
I suggest the commencement of air strikes on military targets in Syria, akin to the operations in Libya.
You want to bomb more people? You want to invade, perhaps?
Yese i am all for bombing mass murderers and tyrants.
Where next? Anywhere else with nasty leaders who do nasty things?
Iran. Then any other dictatorship.
The interfering of nations in the internal politics of other sovereign states has frequently worsened such situations in the past – see Iran as but one example – why would it be any different this time?
Generally the interference of nations in the internal politics of other sovereign states has improved the situation: (1) Germany was better once we had de-nazified it, (2) Japan has been more peaceful and friendly since we removed its government in 1945, (3) Eastern Europe is much freer, more prosperous and friendlier since we interfered to undermine the tyranny of the socialists, (4) Afghanistan poses much less of a threat to Western security since we demolished all the Al-Qaeda training camps, (5) Iraq has been much friendlier to the West since we removed Saddam Hussein.
In contrast we have not interfered in Iran - it remains a bitter enemy committed to regional hegemony, nuclear weaponry and the support of terrorist organisations, nor North Korea which continues to post a threat to the stability of the Pacific.
On top of that, consider this: in this age of austerity, what additional services would you cut to fund those bombs or invasions?
NHS and EU funding.
