Barack Obama has managed to have a pretty decent last year in office. So far, his biggest move of 2016 was endorsing former Secretary of State Hillary Clinton for president.

But in the face of the most hectic presidential race possibly in United States History as well as numerous tragedies and foreign issues galore, President Obama has managed a mostly scandal-free, uncontroversial last year in office.

That is until this week.

The bill which would enable 9/11 survivors and families to sue the Saudi government which passed through the house in May just passed through the Senate with massive bi-partisan support.

Obama has spoken out against this bill on multiple occasions, pushing that the repercussions were the bill to go into law could be disastrous for US-Saudi relations as well as lead to retaliatory measures from Saudi Arabia.

The bill, now dubbed the Justice Against Sponsors of Terrorism Act, spawns from the outrage following declassification of evidence from the 9/11 commission report that Saudi Arabia may have sponsored the terrorists who participated in the September 11^th attacks on Washington DC and New York City, fifteen of whom were Saudi themselves.

The bill was introduced by Democrat Chuck Schumer of New York, who is famous for his strong partisan stance on gun control.

“The victims of 9-11 and other terrorist attacks on US soil have suffered much pain and heartache, but they should not be denied justice”, says Schumer on the progress of the bill and possibility of a veto.

The real kicker in all of this is that the legislation will land on President Obama’s desk on Sunday, the 15^th anniversary of the September 11^th attacks.

This puts Obama in an especially difficult position, as the bill has the mass support of both Democrats and Republicans in the senate and house, who currently have the power to overturn a veto should one be issued.

Barack Obama will have to choose between sticking to his guns and vetoing the bill within the ten days he has to act on it, or allow it to pass into law and allow the citizens of the United States to sue the Saudis for their role in the most deadly attack on the United States.

If this bill is vetoed and then overturned in Congress to become law, then Obama will be viewed as non-objective and the one thing that got in the way of the bill becoming law.

If he passes it, and his predictions prove true and the Saudi government takes legislative action against US citizens as well as damaging US-Saudi ties, then Obama will take the blame for it.

This makes this his biggest challenge of 2016, because of the scale of this bill, the date of its intended signing or vetoing, the bi-partisan support, and it’s intertwining of already delicate domestic and foreign policy.

Time will tell how this all comes out, but until then, the pressure is on President Obama, and this time, he has very few friends to fall back on.
