The crime of the year of the "international community" was the recent departure of all the Western diplomats from Sanaa in Yemen. The official argument was safety. But Sanaa was at that moment still quite safe, so everybody could understand that in reality it was a public rejection of the Houthi's and the announcement that the West would take steps to undermine their government. Once again the West had subscribed to the agenda of the hatred of the Saudi regime.
And indeed we saw soon an increase of Al Qaeda attacks. Former president Hadi escaped mysteriously from Sanaa and - after having moved to Aden - renewed his claim to the presidency. Most likely the Saudi's had spent a lot of money to bribe his guards to let him escape. Hadi's most recent move has been to call for a military intervention by the Gulf States.
I believe it was fundamental mistake to turn on the Houthi's. Like it or like it not: they had conquered the power. So challenging them is interference in the internal affairs of Yemen and setting the country up for a civil war.
