Perhaps you should try some spelling variations:
decrease response » decreased response (Expand search), increased response (Expand search), increases response (Expand search)
response defense » response decrease (Expand search), resource defense (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
or decrease » of decrease (Expand search), not decrease (Expand search), to decrease (Expand search)
and objects » and object (Expand search), and subjects (Expand search), and objectives (Expand search)
defense or » defense of (Expand search), defense on (Expand search), defense in (Expand search)

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( decrease response defense OR decrease ) OR ( decrease NOT decrease AND objects ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease response defense or decrease ) OR ( decrease NOT decrease and objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease response defense or decrease ) OR ( decrease NOT decrease and objects ))*.
