That depends on one's perspective, but I think many would say that the government is doing a very poor job of meeting the goals listed in the Preamble. At the same time, there may be people that believe that government is doing a good job at meeting the goals of the Preamble.
The Constitution describes what it can do and, importantly, what it can legally be prevented from doing. No government anywhere can be compelled to do anything in a positive way, only to stop doing something they have no constitutional authority to do. The US Constitution contains in its preamble general ideas of what the government is morally obliged to do, and of course any elected government is morally obliged to carry out its mandate from the electors, an obligation they usually ignore.

The federal government. They have been doing an amazingly poor job for several decades. We forget that the federal government has power only because they receive it from the people. If we had the guts and drive, the states could initiate changes to the Constitution, and these changes would NOT have to be initiated or approved by the federal government, or any part of it.
The federal government was nearly nonexistent, each state had their own military and currency which made the US more prone to attacks.
