Why terrorism can't win

I, along with most of the rest of the world, was appalled by the Manchester terrorist attack. The terrorists can'e possibly win using these methods, and here I will try to explain why.

1. If their aim is to promote Islam, they are doing a very poor job. They are achieving the very opposite of that, and are turning people against one of the world's great religions. Many reasonable, peaceful Muslems are being targetted, as are mosques, and Islamophobia is getting much stronger. Extremism breeds extremism, so Muslims will be targetted more.
2. I am old enough to have had Parents, Aunts, Uncles and Grandparents who lived through WW2. They talked of that time, almost with fondness and nostalgia. This was because of the solidarity that encompassed the nation. The bombing of the cities and factories, and especially the bombing of Coventry Cathedral, drew people together. This is what I see happening everywhere atrocities are committed now. The French people, the German people, the American people after 9/11 and the Boston bombings, and we the British are all drawn together by this, far from what I think is intended, to disrupt, fragment and induce fear.
3. Then there is determination. Churchill said in his famous speech, when he said, 'We shall defend our island, whatever the cost may be, we shall fight on the beaches, we shall fight on the landing grounds, we shall fight in the fields and in the streets, we shall fight in the hills; we shall never surrender.' The terrorists are stirring this determination in us all.
4. Britain is used to terrorism. IS seems to forget, or has never known, this. We had a long fight with the IRA when London was struck by bombs as were other cities in the country. The IRA did not succeed in 'winning' by making us surrender, and I can't see IS doing so either. In the end, the IRA negotiated a peace. Will IS? What is it they want exactly, anyway?
5. I cannot understand how anyone can think that Allah will be pleased at this slaughter. Surely, He would be better pleased at people being converted to His worship, rather than destroyed. If the aim is to get a Muslim world, then this is not the way to go about it. It brings the religion into disrepute. People will be all the more disinclined to embrace its tenets.

I'm sure there are other reasons why IS cannot succeed using terrorism, but I want to get this post out there. I will ammend it if I think of anything else.

Let's all pray for peace and the cessation of sucn violent attacks
