The report that Russia paid the Taliban bounties to kill Americans is suspect; it may be bogus. The Taliban were fighting the forces in Afghanistan and did not require a special inducement to do that.
If the claim happens to be accurate, we should not exaggerate its significance. In the 1980s, the US did far more than pay Afghans bounties to kill Russians. It recruited them, trained them, and armed them, all under the rubric of "al-Qa'ida". In comparison to that, merely paying bounties would be a tiny matter.
Anyway, bounties are not a reason to keep the war going on and on. The US should pull out its forces and let the Taliban win. Their religious tyranny would deny important human rights, but that's not as bad as war forever.
