Subject
The likely course of political fights in September.
Significance
Amid a climate of partisan tensions and conflicting presidential ambitions, the United States could experience a government shutdown when the fiscal year ends on September 30. Eighteen Republican congressmen have said that they will not vote for any budget that does not cut off funds to Planned Parenthood, a health-services provider. Such a budget would not pass the Senate or be signed by the president, allowing, as in 2013, partisan disagreement on a single issue to shut down much of the federal government.
Impacts
The impact on US credibility would be significant and contribute to an image to its allies of a dysfunctional government.
Nonetheless, it would not break alliances, as many governments, such as those in the Gulf and South-east Asia, have few other options.
However, it would encourage allies to hedge, taking more accommodative positions in Asia and belligerent ones in the Middle East.
