No problem. It is important to note that there is no such thing as an invincible system. Especially if you are trying to defend against the US and/or Israel. In such a case it may be better to simply abandon your post because chances are some weapon made in the US and/or Israel will shorten your days. It is just that some targets are harder than others. If Putin refuses to play ball it doesn't mean that Israel cannot reach out and touch Damascus, even if they get the S-300 and the Yakhont. All it means is slightly more planning on the side of the Israelis, and greater care taken by the pilots and the naval ships. However, the end result will be the same ...smoke over Damascus.
As an aside ...I really wish a different solution could be found. I despise Assad, however those 'rebels' appear to be quite similar to certain Al Qaeda elements.
Anyways ...have a blessed day.
