It’s about UNSC approved CW investigations that Russia had a hissy fit over as they blamed Assad’s govt and ISIt is not about CW investigations. It is about imitations of investigations to produce falsified results without even expection of sites in question.
There were six UNSC approved crossing points for humanitarian aid. That was reduced to two, now none due to another Russian veto.Moscow proposed to leave the main crossing point with 85% of supplies volume. But this proposition was blocked by US/UK/France and others. There is no problem in supplies of humanitarian aid through dozens of crossing points. It is about the regime of special crossing point.
Assad says most of the country including the large urban areas is under his govt’s control yet the millions of displaced are not rushing back. One wonders why life in a refugee camp is adjudged better than under the Assad govt?The main reason is the military conflict that continues in Syria.So thank rebels/insurgents/jihadists/terrorists for impossibility for millions to return.
