The Rhetoric from Hamas (militant organisation who seek Palestines liberation, also deemed a terrorist organisation by numerous countries and organisations such as the UK), who are backed by Iran is literally we will wipe Israel (jews) off the planet. After having the Nazis and other groups attempt to do that previously, there is definitely an argument that Israel are defending themselves and have the right to do so.
Would you ever feel comfortable with a neighbour who is a murderer of a member of your family even if you owned an arsenal of guns and had the police in a car watching your property?
Palestine isn’t recognised globally as a country whilst Israel is a ‘Western’ country in the middle East and the ally of many countries such as the UK and USA.
Also Palestine and Hamas are not the same thing. Its like sayingb the KKK is representative of all of the USA.
The whole situation from its inception after ww2 to now is fucked.
