South Korea will consider supplying arms to Ukraine

No more inefficient than shipping Korean cars, phones and washing machines, which is to say that transportation costs are a mere drop in the bucket.

Is it really much more difficult or inefficient than the US and Canada shipping arms? Is that extra worth it?

Considering that Russia and North Korea are increasing ties, announced at Putin's recent visit, it's likely in SK interest to aid Ukraine so that Russia has to allocate mil hardware to their fight rather than selling it to NK. This just happened with India, who decided to go with US hardware because Russia has continuously delated delivery of systems they already bought.

What a ridiculous comment!

Have you any idea how cheap shipping is?
