Bullets can't kill terrorism only the individual terrorist. Add to that a religious terrorist brainwashed since birth by primitive religion who actually believes that divine right is on his side and the invasions of Iraq and Afghanistan can only breed more hatred towards the West for which our own people will suffer sporadically over many years just as they did with the IRA. Muslim extremism will not be stamped out by the savagery of war hardened US and UK troops in these countries it will only bring more extremists to the front line.
In the meantime our own services such as the NHS are at breaking point financially and cancer victims are refused drugs because the country can't afford them.
