The answers of "yes" or "no" are not good in my opinion especially to this kind of questions. I'm Palestinian but I will try to see this from 2 different angles. Read if you want to know:
Hamas is considered a terrorist organization by the USA and E.U, thus most of the people living in those countries consider Hamas a terrorist group. Moreover, these people say that Israel has the right to exist on the Palestinian lands occupied in 1948. People in the USA and Europe say that the Jewish people were persecuted (it's 100% true, and Europeans persecuted them not the Palestinians nor Muslims) and they have the right to have their national homeland based on the "Jewish nationality". Also, in the Holy books in those countries, God has said that the land of Israel is for the Israelis only. This gives people in Europe and America a strong motive to think that Israel has the right to exist regardless of the methods. Honestly, if I were living in Europe watching the biased media and reading the holy books I might think that Hamas is a terrorist group.
For the Palestinians, Palestine is their country, was occupied by Zionists in 1948, then the State of Israel emerged and was recognized (as we mentioned before). For the Palestinians, Israel was created on their stolen lands which they lived in thousands of years ago, thus -rationally- it doesn't have the right to exist (Jews have the right to exist of course in Palestine as they always did, but they don't have the right to create a state on the Palestinian stolen lands). The aim of the Palestinian resistance (Hamas and others) is to liberate Palestine not to kill (of course killings is one of the methods since U.N resolutions are not respected by Israel). Hamas has stated: Our conflict with you (Israelis) is not religious but political. We have no problem with Jews who have not attacked us — our problem is with those who came to our land, imposed themselves on us by force, destroyed our society and banished our people". Therefore, for the Palestinians including Hamas killing people is not an interest nor legalized without a reason. So Hamas in not a terrorist group for these people. And for Muslims i.e. Palestinians Jews have the right to practice their religion in Palestine "the Holy Land", again Hamas stated : "Our message to the Israelis is this: We do not fight you because you belong to a certain faith or culture. Jews have lived in the Muslim world for 13 centuries in peace and harmony; they are in our religion "the people of the book" who have a covenant from God and his messenger, Muhammad (peace be upon him), to be respected and protected." The Palestinians now realized that the whole world stands on Israel's side, especially after the PA elections when Hamas was democratically elected, they saw that the USA and E.U were ready to punish them for their choice by cutting funds and putting obstacles in front of transferring money to the West Bank. The Palestinians don’t see any hope when they hear the world promising them to spread peace in the region, and on the other side supporting Israel against them.
I think this is a short brief of how people think and believe. And I strongly hope it helps for better understanding between us, which means “peace and harmony for both” as I believe. And my message to people: “don’t take all what you see on media for granted, try to listen to the opinions of people living in this conflict. And your beliefs are well-respected, but they don’t interest other people, so don’t try to impose them”.
Peace on you all…..
