We are preparing against sanctions for a time. We already have hidden embargo on military products including high tech raw materials. We had this before at 1974 cyprus operation and we are experienced. Actually thanks to that embargo we have built all those defence firms. At the long term that embargo became very very benefiacial. Plus; today things are different, we are really ahead of 74 conditions.
There were news those indicated that we have stockpiled a lot of spare parts for air force. The highest dependency is on air force but at the short term embargo will not effect us. When we are out of spare parts(especially turbine blades etc) it might effect us but still we have programs to handle that problem. (Especially material and production R&D)
example of news:
https://nationalinterest.org/blog/b...d-getting-russian-s-400-anti-air-system-69382
Missiles are not a problem. We are really good at those now, producing most of them. We a large military and large stockpiles. At the short term low and medium altitude anti-air missiles will be ready, high altitude is done with S400.
I think if we get military embargo it will not affect us at the short term because of stocks and it will not effect us at the long term thanks to ongoing programs. If we get a problem we can conduct business with other countries.
