NATO is playing with fire. And yes it will be no help.It will get destroyed in no time by the Russian forces or missiles, very small quantity may get passed, but not much and meaningful
btw, what weapon we are talking about?, I think it is just for a show of solidarity
All the professional Ukrainian army troops are bottled up in the East of Ukraine.
Whichever weapons these are would be given to civilians to die needlessly.
The Ukrainians are already forcefully conscripting men trying to leave via the Polish border.
These will be civilians probably with families who were just trying to escape.
If they did give them proper air defense systems like they claimed you would need trained staff to operate them. Not civilians.
