war of choice by Israel and the US.
Let's bring it a bit nearer to home.
You live on a block of flats. One of your neighbours has always been a bit angry, unpredictable, threatening other neighbours.
One day they announce they will start killing others in the block of flats if they don't do as they want. Also because they are on the bottom level are always interfering with people's lawful business entering and leaving.
Would you tolerate such behaviour, or do something about it personally, or maybe get the authorities to deal with this person.
