Birthdays are supposed to be times for celebration and gift-giving. But America’s upcoming birthday on the Fourth of July is a time when the gift most needed is an urgent warning about the dangers of losing the things that have made this country America — and have long made “America” a ringing word of freedom, not only in this country but to people around the world.

All is not lost. But all could be lost — especially if too many of us take freedom for granted and focus our attention on other things, like electronic gadgets and the antics of celebrities, while ignoring such dangers as nuclear weapons in the hands of suicidal fanatics, with a track record of savagery, whom we are too squeamish to call anything stronger than “militants.”

Nor are all the dangers abroad. Within our own country, there are all too many signs of people blithely ready to sacrifice the interests or freedom of Americans for the sake of symbolism or passing fashions.

When a former Speaker of the House of Representatives announces that she is going down to our border to greet and welcome masses of people crossing that border illegally, you know that something is fundamentally wrong. No one knows, or apparently cares, what diseases these floods of illegals are bringing into the country, including diseases that have been largely stamped out in the United States, and which American doctors have seldom seen enough to know how to spot them or treat them.

No one knows, or apparently cares, how many of these “children” include teenage criminal gangs to whom murder is no big deal. Worst of all, no one knows, or apparently cares, that the elected representatives of the American people were cut out of the loop when it came to making these decisions. All that matters to people like Nancy Pelosi is the symbolism of welcoming the oppressed, especially if they represent more votes for Democrats, who will shower the taxpayers’ money on them.

As if to make clear the elite’s contempt for ordinary Americans’ intelligence, President Barack Obama tells us that the people crossing the border “love” America. How could he possibly know that?

Arrogant abuse of power does not end with the federal government. In Massachusetts, teenager Justina Pelletier was taken from her parents’ custody and held virtually incommunicado for over a year, because her parents preferred to continue to have her treated as the physicians at a medical facility associated with Tufts University had treated her, even though shrinks at Children’s Hospital in Boston said her problems were in her head, and took her off some of her medications.

This difference of opinion as to the best medical treatment for Justina Pelletier was enough to get a judge to side with headstrong bureaucrats and override her parents’ rights. So a girl who was ice skating before ended up in a wheelchair under the “care” of shrinks.

Fortunately, enough media attention, especially by former governor Mike Huckabee on Fox News Channel, finally got this child freed. Perhaps we can hope that all is not lost — yet. But if this case is a symbol of Americans fighting back, it is also a symbol of why it is desperately important to fight back.

That spirit is the best birthday present for America.
