Looks like your English comprehension is very weak, let me break it down for you so you could understand it properly
1st tweet = " Dawn Leaks was a deliberate attempt to malign the Army and Government must immediately make public the complete inquiry report"
2nd tweet = " Dawn Leaks was never about army & government. It was about national security. The whole nation needs to know what was settled".
Maligning the army is a national security issue, everyone agreed to that. He hasn't accused anyone of it. In the second he specified that Dawn Leaks was more than just a confrontation between the Army and the civilian government, and he reconfirmed that it is a national security issue.
Now tell me where is the U-Turn?
