1. Iraq unsuccessfully tried to occupy iran and then kuwait. Itz important that the dog called iraq infected with rabis be put in a cage. America has the technology/courage and finances to take up the task. kudos to them, though i think they have their own vested interests in doing so.
2. The palastine and arab conflict is in existence since ages. Only jesus/allah know who owned those lands initially.
3. Iran is an islamic country and history suggests that no islamic country is worth believing. They never do broad thinking and act more on religious grounds/sharia laws than humanitarian. So, it is important for the world to keep iran away from nuclear technology .
4. Afghanistan is torn between cold war between usa and ussr. later, neither of them have cared to help it and hence it has become a den for jihadi groups. i THINK hamid karzai is trying his best to restore its previous charisma.
