A cyber attack has taken down the online booking system for Ukraine’s trains.

All over the country people are lining up to buy tickets in person. Staff are working extremely long hours to serve everyone.

This is a very resilient country.

Some of the units in Ukraine are doing this hundreds of times a week. Air defence at scale is hard. Doing it affordably is harder.

Ukraine uses the lowest cost interceptor whenever it can. Often the cost to intercept is cheaper than what they are shooting down.

There's still something about this deal that feels extremely exploitative of Ukraine and damaging the reputation of the United States. Allies should not have to bargain for "the right to fight on".
