If you think an artillery bombardment and airstrike preempting a lone mercenary infantry force's assault on an oil refinery shows military superiority of one nation over another, you are hopelessly lost.
Thats pretty much completely accurate, however im still confused as to why US is even allowed in Syria since i believe they are technically illegally in Syria, which is a sovereign country (Russia is in there legally)
The US is fighting a proxy war in Syria to topple Assad because Assad nationalized Syria's oil industry and bank and the American political establishment which is an apparatus for major firms wants said firms to have access to international markets without competition.
The US is fighting a proxy war in Syria to weaken Syria (or even creating a puppet government) and creating an emigration flow to Europe as that is what the people hidden behind the US government want.
