Boston Globe, please define “threat”

The Globe headline reads:

Democrats renew threat to go it alone

The lede:

There's quite a bit of buzz today that Democrats might go it alone on a health care overhaul, giving up on a bipartisan bill because of Republican intransigence and unwillingness to compromise.

How is that a “threat”? Aren't Democrats simply acknowledging the facts on the ground, which seem to indicate that Republicans, once again, might uniformly oppose Obama's legislation? How are Democrats threatening to go it alone if it's Republicans who won't join in? To me, threatening to go it alone suggest Democrats don't want Republican support; that they're rejecting it and telling the GOP to get lost.

A better headline:

Democrats acknowledge they may have to go it alone
