Israel politicians etc. must remain calm and really weigh their words. Threats should be avoided. Now, as far as we know, the missiles haven´t arrive and whether they will do remains to be seen. It should also be said the Russian position in this issue is a reaction to the EU decision. A wise move from Israel is to explain the consequences of the EU decision and try to reverse it. If Russia goes ahead with the delivery of the missiles, most likely and during a long period, Russians will be responsible of them. Threatening to bomb Russians are not wise.
