Scottish independence referendum produced its verdict: people chose to keep the “status quo”. In fact, 55,30%  of Scottish voters (about 2 million votes) answered “no” to the question “do you want to obtain independence?” .

United States president Barak Obama authorised airstrike in Iraq against Islamic State (IS) Sunni jihadist militias. There are no doubts that US intervention could make a difference, but the real question is: by how much?
