The phrase "Americans finally woke up" is a subjective statement and can be interpreted in various ways depending on the context. It could refer to a political awakening, a social awareness, or a change in public sentiment on a particular issue. However, without further context, I cannot determine the specific interpretation or the person or group being referred to as "glad."
