4. Funding
Where exactly does a rebel jihad group like ISIS get funding to carry out such large-scale military operations and occupy vast territory? The main source of income for the jihad organization is the revenue generated from captured oil fields, which is the reason several bans have been imposed on crude from this region. Despite the efforts made by the West to stop this influx of cash, analysts estimate that ISIS earns around $1 million per day from the export of oil.
