You must not understand economics. Those industries exist there not because of a monopoly on resource, like say oil producing nations, but because that is the most efficient place according to the markets. There are plenty of other places capable of filling the gap. Your statement that Putin would control the chip supply is patently incorrect, as if he took the resources and niche that Ukraine holds other nations would simply fill in the gap. This is not like 1991 where Saddam controlling Kuwait gave him a serious percentage of the worlds supply of something.
