Hamas will never be expunged. The Islamist group belongs to the Muslim Brothers organisation whose ideology has taken root in a number of Arab countries in the Levant and in the Arabian Peninsula since one century.
How can you eradicate an ideology deeply rooted in the mindset of communities having a profound political and religious identity?
Those who advocate such ill-conceived and self-defeating ideas have to be seen as nothing but politically and culturally delusional folks unable to learn from past failed bloody experiences.
Very sad indeed.
