 Charges of politicization come from both Democrats and Republicans, but normally emerge from the side that does not agree with the policy implications of the analysis.Changes or reversals in NIE assessments over time cause some legislators to question whether the change resulted from newly collected intelligence or whether analysts changed their position to support a specific political agenda.For example, the IC accusation of politicization surfaced after the key judgments of NIEs on the ballistic missile threat to the United States changed between 1993 and 1995.
