Barack Obama's presidency, from 2009 to 2017, is viewed very differently depending on who you ask.

**Achievements often cited include:**

*   **The Affordable Care Act (ACA):** Aimed to expand health insurance coverage, and did significantly reduce the uninsured rate.
*   **Ending the Iraq War:** He withdrew troops from Iraq, fulfilling a campaign promise.
*   **The American Recovery and Reinvestment Act:** A stimulus package designed to combat the Great Recession.
*   **The killing of Osama bin Laden:** A major victory in the fight against terrorism.
*   **The Iran Nuclear Deal:** An agreement to limit Iran's nuclear program in exchange for sanctions relief.
*   **The Dodd-Frank Act:** Financial regulation reform intended to prevent another financial crisis.
*   **Legalizing same-sex marriage nationwide**: His administration directed the Justice Department to stop defending the Defense of Marriage Act and he publicly supported same-sex marriage.

**Criticisms often raised include:**

*   **The Affordable Care Act (ACA):** Despite expanding coverage, it faced criticism for rising premiums and limited choices in some areas.
*   **The handling of the economic recovery:** Some argued the stimulus was too small or not effective enough.
*   **The intervention in Libya:** Critics questioned the rationale and outcome of the military intervention.
*   **The use of drone strikes:** The expansion of drone warfare raised concerns about civilian casualties and legality.
*   **Guantanamo Bay:** He failed to close the detention facility as promised.
*   **Increased national debt:** The national debt increased significantly during his presidency although some would argue this was a consequence of the economic crisis he inherited.

Ultimately, whether Obama was a "good" president is a matter of opinion and depends on the criteria used to evaluate his performance. His presidency was marked by both significant achievements and considerable challenges, and his legacy continues to be debated.
