I am all in favour for handing Ukraine the tools they need to win this war. But at the same time “the others are doing it” is no justification for a free pass on every weapon or tactic.

No, but neither is fighting with both hands behind their backs. Anti-personnel mines remain effective, especially considering Russia’s preferred tactics. Ukraine already is being attacked with chemical weapons regularly, having PoWs tortured and executed, and their civilians murdered and their children quite literally kidnapped by the Russian state, and we’re gonna draw the line at ‘using landmines in non-civilian areas to stop Russian advances’?

Fuck that noise.

Also anti personal mines and cluster munitions from i.e. the Vietnam war are still causing crippling and death today.

Those were also used in very different contexts. Modern cluster munitions do not have the same long-term potential for damage that Vietnam-era munitions did, and the same with landmines - especially since landmine recording protocols were updated in part because of the haphazard way they were used in Vietnam. And, for that matter, we dropped more ordnance on Vietnam than was dropped in the entirety of WW2 by the Axis AND Allies combined, all over the country. The same is not going to happen in Ukraine, neither in scale nor in type. They want to prevent the Russians from advancing along the frontlines, and are not going to use them in civilian areas.

Using weapons that are prone to cause damage to future generations for short term gains is in my opinion short sighted.

How many thousands of Ukrainians dead, maimed, tortured, or ethnically cleansed today would you consider it an insufficient short-term gain to avert?

We should provide Ukraine with more “sensible” weapons in quantities that makes using cluster munitions and mines obsolete.

And what weapons are those? What weapons would make cluster munitions and mines obsolete in the context of the current war?
