President Trump launches missile strike against Syria
What do you think Putins objective in Syria is? - to keep Assad and his regime going. Russian naval bases on Syria's coast are then guaranteed .
Do you think Putin is interested in stopping the refugee crisis? - while the Syrian war rages on, Putin may well want to flood Europe with refugees. The EU is complicit in this (some EU countries have taken a relatively large amount of refugees in a short amount of time, without bothering to consult the citizens of those countries).
that Assad is the only alternative to ISIS in Syria - what are the other alternatives?
