Are there any “just” wars?

Throughout history many wars have been proclaimed “just..." by those who started them. As the United Nations Charter very clearly indicates, an armed conflict may only be initiated when preventive mechanisms have failed, and all –or a large majority- of countries deem confrontation with the aggressor warranted. Confrontation may become inevitable, but it is not "just".

Once again, Forges’ masterly comic strip, published in "El País" on March 22, says it better than any treatise could:

There are not just wars and unjust wars: there are only abominable wars

How could you paint it in the sky?

Because the truth is written even in the air
