Mirage 2000, Rafale, and Typhoon were/are all arguably designed with a huge emphasis on energy maneuverability, which is also only meant for dogfights according to postings on internet forums. And there are plenty of other isolated ways you could argue the reverse of the US showing restraint in ways others don't, such as Europe's love for delta wings (rejected most recently when the F-35 was first considered), or the Russkies' obsession with supermaneuverability, which the US has barely even considered sane enough for demonstrators. In terms of "mawr dakka", too, assuming you're referring to the A-10, that honor also belongs not to the US, per popular opinion, but to the Soviets in the MiG-27. You've just never heard of it because they wanted to fire essentially the same projectile in a slightly bigger casing at 2000 more rounds per minute, which the airframe simply couldn't handle reliably, and were also limited in the battles they did see due to an unusual weakness to ground fire as opposed to the A-10's unusual resiliency. And besides that, the US also built the F-111 and F-117 as an explicit alternative to light air attack craft.
The only "American thing" that really exists in modern military history is a tendency to do more things than everyone else. The US has NIH-ed their way into pretty much every military technology that's been hypothesized by someone not wearing a tinfoil hat and raving about Nikola Tesla or Leonardo Da Vinci. The public hears about questions like dogfighting and firepower in US aircraft because the US is one of the only countries in the world whose military actively seeks out (or at least sought out, there's some argument that the F-35 is the beginning of the end) multiple home-grown variants of military equipment, especially aircraft, that are expected to compete both on economic and doctrinal value as actual service craft for continuing contracts, rather then just proving ground test beds. More chances to change preference, more chances for contracts, more argument, more buzz filtering into newspapers. In contrast, we're probably not going to talk much about if stealth is a Finnish thing or whatever else for quite some time after this. Perhaps the American thing is spending lots of money, but a full assessment doesn't really allow for more specifics than that.
