Ju,blat is always known to be the superstar of the movie " gone with the wind-part2"! Or we can say the hero of the quote that says : "go with the flow".
Ever heard abou the cameleon that changes its color according to the place it's into!? This is jumbi, but talking politically, i think that the article of Ibrahim el Amin describes what going into his mind the best and why he is doing this:
وكان أن سمع العبارة الفرنسية السحرية: لا مجال لتجاوز سوريا في الملف اللبناني.
داخلياً، كان جنبلاط يشعر بالخناق يضيق عليه
when he feels like that, he will kiss the syrian ass if it needs to.
After all, this is Jumblat!
