Washington Post journalism about Russian withdrawal from Syria

The Washington Post had an article the other day that Hizbullah is freaking out and "shocked" about Russian withdrawal from Syria, and it cited an unnamed Hizbullah official.  In this article, Hasan `Illayq of Al-Akhbar (who has close access to Hizbullah leadership) writes that Hizbullah and Syria were informed in advance of Russian decision. Who do you believe?  In my case, Hasan any day of the week.
