it would seem anti-American sentiment pervades everything these days. the abrams has actually proved quite capable and effective whenever applied. due to the nature of a MBT all of them are vulnerable in an urban setting. which is why they are never fielded without support troops.(a principle learned and utilized since WWII) all modern MBTs are on equal footing these days. although i would say the Merkava has a slight edge with the new point defense system the Israelis are fielding. im not sure where your facts come from concerning Abrams vs Merkava exercises, but i find these so called exercises a bit miss leading as they assume a 1 shot kill. simply not a real world application.

giving the ambiguous nature of this kind of show i think they were quite fair with the results. i see it as an entertaining look at various tanks through the decades. its really hard to compare a WWI tank to a modern tank with any kind of objectiveness as they are so vastly different.
