Wait who abandoned Ukraine?

Sanctions don't count. When people are dying sanctions don't count.

There are nuclear treaties that prevent stationing and mobility of NATO troops and armaments in the Baltic, Ukraine isn't even a member of NATO, and they are getting far more than mere sanctions - intelligence, equipment, financial aid, strategic advice, political and global media support to name a few.

NATO can't just abandon nuclear treaties. And trust that, as it controls 90% of the pipeline of oil between Russia and Europe and that because the conflict arose during highly contented offers for Ukraine to join the EU, that NATO is doing everything it can.

It would have collateral effects (disabling all wireless activity in the area of jamming), but it's absolutely possible.

>disabling all wireless activity in the area of jamming Only on the jammed frequencies. Police radios and such will keep working.

Weeelll... that depends on a lot of things. Any jammer with the power to work over a meaningful radius in this context is probably going to throw out lots of spurious emissions in neighboring bands.

If the authorities sought to disrupt these networks, would it not be possible to jam Bluetooth (and Wi-Fi) signals within a certain area?

Authorities could also produce rogue clients that spam malicious messages--depends how resilient FireChat's protocol is and how well it filters noise (I might be talking FUD though as I haven't tried it).

Moreover, there's no way to police bad actors in a local mesh, and no global blockchain you can trust.

I wanted to like FireChat, as it was previously possible to use it entirely offline, in a purely P2P fashion.

While this is still possible, you are now forced to first create an account online, and subscribe to a bunch of internet-based channels, before the app will let you use the P2P portion.

This is frustrating. The market is wide open for someone to make a pure P2P communications app that doesn't require internet access at all, even initially.

Police Radios (and GMRS, and FRS) are not neighboring bands to 802.11
