I looked up what the atheist ex-PM of Greek Alexis Tsipras had to say about the war, and for once, I partly disagree with him. Only partly. He says he feels it was a mistake to send weapons into Ukraine, rather than humanitarian aid. I think that either of them is really inadequate, and I will tell you my reasoning as to why.
I believe that communications technology and the means of powering it is what would eventually emancipate Ukraine while preserving its infrastructure. It sounds to me like the stalling of the Russian advance upon Kyiv has been accomplished partly based on successful strategy tactics, and I suspect that civilian participation has played at least some role in that.
Due to probable energy problems, fully charged energy banks for phones would probably be welcome. I suspect that it might also be a good idea to try to get systems running there that could create private local networks that could be used for coordinating efforts within a radius of a couple of blocks.
Such technology would serve multiple purposes:
A) Ukrainians would need strong internal communications in order to fight back against propaganda. Unfortunately, the average person can be highly credulous, and sufficient saturation with persistent propaganda, without other inputs, actually CAN gas light the weaker minded members of a population into believing just about anything. However, strong internal communications could give even simple, everyday individuals opportunities to hear what is actually going on locally.
B) furthermore, they would be better able to coordinate another movement like the Euromaidan movement against any occupation government that the Russians installed, thereby putting the Russians back to square one: pre-Maidan, Russia basically controlled Ukraine through the strings they had attached to the jumping jacks that previously held sway in Ukraine, so they were independent in name only. Euromaidan was only possible due to the strong internal communications among the people of Ukraine.
C) it is also relevant that locals would need communications technology to coordinate a civilian resistance, which can be done fully without guns as long as you have a few talented chemists and a few experienced rugby players on your team but cannot be done without good internal communications. However, they would also need such technology and tactics in order to coordinate rescue operations. With the right technology, the people that DID have good knowledge about field medicine could communicate directly with people that were on the scene, miles away, to walk them through setting a broken leg, cleaning a wound, stopping blood flow, and so on.
D) fighting against loneliness would also help to preserve morale. People hiding in their basements from missiles raining down could eventually just lose hope if they did not have contact with family far away and overseas. As a zoophile, I have to confess that I have trouble finding people in my face-to-face life that I can talk to openly and honestly, and I depend heavily on access to the Internet for community and friendship with people that I can open my heart to. The people that I talk to online are not just anonymous strangers on the Internet to me, but we send gifts to each other every Christmas. We know each others' real names. Even though they live very far away, often in other countries, I love them like kin.
Therefore, I would contend that Alexis Tsipras is only partway right: weapons are only as inadequate, by themselves, as humanitarian aid. In the end, I think that the best service that has been done for Ukraine, so far, has been for Elon Musk to give them access to Starlink. Yes, I know that Musk is an imperfect person, but let's give the devil his due: it was pretty cool that he responded almost immediately to a request by Ukraine's leader. I don't ask people to be perfect, but I ask them to do the right thing when it counts the most.
Communications technology is what made Euromaidan possible. Communications technology is what people need in order to resist efforts at using destructive propaganda to divide them against themselves. Communications technology can save lives. Communications technology is how ordinary people can fight back. Communications technology helps fight back against the slow killer that is loneliness. Communications technology would round out the other efforts that have been made to help Ukraine in this hour.
