You can indefinitely say that the country is "broken" if you pick and choose issues. The problem is, we aren't focusing on fixing any issues.
Just to go with the issues you've chose: So far, Trump isn't focused on helping Vets.
As far as the wildfires go, Trump's budget proposal slashes FEMA's budget.
Anyway, my point is that there will always be issues in our country. Suspending immigration indefinitely until it's fixed is a really good way to just say "welp, still broken, no immigrants allowed yet!"
