Do you think ISIS can be negotiated with... really?
It's a tricky one. We used to say that we couldn't negotiate with the IRA too. Or ETA.
You can't really make that comparison.
The IRA was strictly a local group that attacked the British in Ireland and in England.
The ETA were similar but were based in the Basque Country and attacked the Spanish and the French.
Neither group...
► used brainwashed members with no fear of death as suicide bombers
► declared war on the rest of the world
► had tens of thousand of followers world-wide traveling to Ireland/Basque Country to join in the fight
► had followers world-wide carrying out terrorist acts.
The IRA were always willing to negotiate, its just that what they wanted (a unified Ireland and the British out of Ireland completely) was totally unacceptable to the British. It was the British Government who refused to negotiate.
Likewise, ETA wanted independence for the Basque provinces of Álava, Biscay and Gipuzkoa (in Spain) and Labourd, Basse-Navarre and Soule (in France). and were willing to negotiate for it. Neither France or Spain were willing to have talks.
ISIS, on the other hand, are totally uninterested negotiating. They have no a specific aim beyond controlling the rubble pile that is their patch of ground. They appear to be an angry horde of insane individuals who routinely murder people over what they wear, what they say and what they believe. They consider anyone who is not of their unique form of Islam has no right to be alive. Every single one of us non-believers; you, me, everyone on this forum, in all our respective countries, is Infidel, and is therefore marked for execution. We all have targets on our backs.
Negotiation with groups of this type of mentality and holding this kind of belief system, is impossible. There are only two things you can do;
1. Put yourself behind an impenetrable wall and hope that it really is impenetrable.
2. Wipe them out before they wipe you out.
